GENERAL DESCRIPTION
The ADV®7324 is a high speed, digital-to-analog encoder on a
single monolithic chip. It includes six high speed NSV video
DACs with TTL-compatible inputs. It has separate 8-/10-,
16-/20-, and 24-/30-bit input ports that accept data in high
definition (HD) and/or standard definition (SD) video format.
For all standards, external horizontal, vertical, and blanking
signals, or EAV/SAV timing codes, control the insertion of
appropriate synchronization signals into the digital data stream
and, therefore, the output signal.

The ADV7324 is a Pb-free, environmentally friendly product. It is
manufactured using the most up-to-date materials and processes.
The coating on the leads of each device is 100% pure Sn electro-
plate. The device is suitable for Pb-free applications and is able
to withstand surface-mount soldering up to 255°C ( 5°C).
In addition, it is backward-compatible with conventional SnPb
soldering processes. This means that the electroplated Sn coating
can be soldered with Sn/Pb solder pastes at conventional reflow
temperatures of 220°C to 235°C.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
this product features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

ADV7324
MPU PORT DESCRIPTION
The ADV7324 supports a 2-wire serial (I2C-compatible)
microprocessor bus driving multiple peripherals. This port
operates in an open-drain configuration. Two inputs, serial data
(SDA) and serial clock (SCL), carry information between any
device connected to the bus and the ADV7324. Each slave
device is recognized by a unique address. The ADV7324 has
four possible slave addresses for both read and write operations.
These are unique addresses for each device and are illustrated in
Figure 44. The LSB sets either a read or write operation. Logic 1
corresponds to a read operation, while Logic 0 corresponds to a
write operation. A1 is enabled by setting the ALSB pin of the
ADV7324 to Logic 0 or Logic 1. When ALSB is set to 1, there is
greater input bandwidth on the I2C lines, which allows high
speed data transfers on this bus. When ALSB is set to 0, there is
reduced input bandwidth on the I2C lines, which means that
pulses of less than 50 ns will not pass into the I2C internal
controller. This mode is recommended for noisy systems.
The ADV7324 acts as a standard slave device on the bus. The
data on the SDA pin is eight bits long, supporting the 7-bit
address plus the R/ bit. It interprets the first byte as the device
W
address and the second byte as the starting subaddress. There is
a subaddress auto-increment facility. This allows data to be
written to or read from registers in ascending subaddress
sequence, starting at any valid subaddress. A data transfer is
always terminated by a stop condition. The user can also access
any unique subaddress register on a one-by-one basis without
updating all of the registers.
Stop and start conditions can be detected at any stage during
the data transfer. If these conditions are asserted out of
sequence with normal read and write operations, they cause the
device to immediately jump to the idle condition. During a
given SCL high period, the user should only issue a start
condition, a stop condition, or a stop condition followed by a
start condition. If an invalid subaddress is issued by the user,
the ADV7324 does not issue an acknowledge and returns to the
idle condition. If the user utilizes the auto-increment method of
addressing the encoder and exceeds the highest subaddress, the
following actions are taken:

• In read mode, the highest subaddress register contents are

indicates the end of a read. A no acknowledge condition is

• In write mode, the data for the invalid byte is not loaded into
any subaddress register, a no acknowledge is issued by the
ADV7324, and the part returns to the idle condition.
To control the various devices on the bus, the following
protocol must be followed. First, the master initiates a data
transfer by establishing a start condition, defined by a high-to-
low transition on SDA while SCL remains high. This indicates
that an address/data stream will follow. All peripherals respond
to the start condition and shift the next eight bits (7-bit address
Before writing to the subcarrier frequency registers, it is required
to reset ADV7324 at least once after power-up.
The four subcarrier frequency registers must be updated,
starting with Subcarrier Frequency Register 0 and ending with
Subcarrier Frequency Register 3. The subcarrier frequency will
only update after the last subcarrier frequency register byte has
been received by the ADV7324.
+ R/ bit). The bits are transferred from MSB down to LSB.
W
The peripheral that recognizes the transmitted address
responds by pulling the data line low during the ninth clock
pulse. This is known as an acknowledge bit. All other devices
withdraw from the bus at this point and maintain an idle
condition. The idle condition is where the device monitors the
SDA and SCL lines, waiting for the start condition and the
Figure 45 illustrates an example of data transfer for a write
sequence and the start and stop conditions. Figure 46 shows bus
write and read sequences.
correct transmitted address. The R/ bit determines the
W
direction of the data.
Logic 0 on the LSB of the first byte means that the master will
write information to the peripheral. Logic 1 on the LSB of the
first byte means that the master will read information from the
peripheral.

REGISTER ACCESS
The MPU can write to or read from all registers of the
REGISTER PROGRAMMING
ADV7324 except the subaddress registers, which are write only
registers. The subaddress register selected determines which
register the next read or write operation will access. All
communication with the part through the bus starts with an
access to the subaddress register. A read/write operation is then
performed from/to the target address, which increments to the
next address until a stop command is performed on the bus.
The following tables describe the functionality of each register. All
registers can be read from and written to, unless otherwise stated.
SUBADDRESS REGISTERS (SR7 TO SR0)
Each subaddress register is an 8-bit, write only register. After the
encoder’s bus is accessed and a read or write operation is selected,
the subaddress is set up. The subaddress register determines to
or from which register the operation takes place.

INPUT CONFIGURATION
When 10-bit input data is applied, the following bits must be set
to 1:
PS ONLY OR HDTV ONLY
Address[0x01]: Input Mode = 001 or 010, Respectively
Address 0x13, Bit 2 (HD 10-bit enable)
Address 0x48, Bit 4 (SD 10-bit enable)
YCrCb PS, HDTV, or any other HD YCrCb data can be input in
4:2:2 or 4:4:4. In 4:2:2 input format, the Y data is input on Pin Y9
to Pin Y0, and the CrCb data is input on Pin C9 to Pin C0. In
4:4:4 input mode, Y data is input on Pin Y9 to Pin Y0, Cb data is
input on Pin C9 to Pin C0, and Cr data is input on Pin S9 to
Pin S0. If the YCrCb data does not conform to SMPTE 293M
(525p), ITU-R BT.1358M (625p), SMPTE 274M (1080i),
SMPTE 296M (720p), SMPTE 240M (1035i), or BTA-T1004/1362,
the async timing mode must be used. RGB data can only be
input in 4:4:4 format in PS or HDTV input modes when HD RGB
input is enabled. G data is input on Pin Y9 to Pin Y0, R data is
input on Pin S9 to Pin S0, and B data is input on Pin C9 to Pin C0.
The clock signal must be input on Pin CLKIN_A.
Note that the ADV7324 defaults to simultaneous SD and PS
upon power-up (Address[0x01]: Input Mode = 011).
SD ONLY
Address[0x01]: Input Mode = 000
In 8-/10-bit input mode, multiplexed data is input on Pin S9 to
Pin S0 (or Pin Y9 to Pin Y0, depending on Register Address 0x01,
Bit 7), with S0 being the LSB in 10-bit input mode (see Table 21).
Input standards supported are ITU-R BT.601/656. In 16-/20-bit
input mode, the Y pixel data is input on Pin S9 to Pin S2, and
CrCb data is input on Pin Y9 to Pin Y2 (see Table 21).

When Register 0x01, Bit 7 = 0, CrCb data is input on the Y bus,
and Y data is input on the S bus. When Register 0x01, Bit 7 = 1,
CrCb data is input on the C bus, and Y data is input on Y bus.

YCrCb PS and HD data must be input in 4:2:2 format. In 4:2:2
input format, the HD Y data is input on Pin Y9 to Pin Y0, and
the HD CrCb data is input on Pin C9 to Pin C0. If PS 4:2:2 data is
inter-leaved onto a single 10-bit bus, Pin Y9 to Pin Y0 are used
for the input port. The input data is input at 27 MHz, with the
data being clocked upon the rising and falling edges of the input
clock. The input mode register at Address 0x01 is set accordingly.
If the YCrCb data does not conform to SMPTE 293M (525p),
ITU-R BT.1358M (625p), SMPTE 274M (1080i), SMPTE 296M
(720p), SMPTE 240M (1035i), or BTA-T1004, the async timing
mode must be used.

DATA
In simultaneous SD/HD input mode, if the two clock phases
differ by less than 9.25 ns or by more than 27.75 ns, the clock
align bit [Address 0x01, Bit 3] must be set accordingly. If the
application uses the same clock source for both SD and PS, the
clock align bit must be set because the phase difference between
both inputs is less than 9.25 ns.
WITH A 54MHz CLOCK, THE DATA IS LATCHED ON EVERY RISING EDGE.

reset when the SD RTC/TR/SCR control bits at
Address 0x44 are set to 01.
HD TIMING RESET
A timing reset is achieved by toggling the HD timing reset control
bit [Subaddress 0x14, Bit 0] from 0 to 1. In this state, the horizontal
and vertical counters remain reset. When this bit is set back to 0,
the internal counters resume counting.
This reset signal must be held high for a minimum of
one clock cycle.
The minimum time the pin must be held high is one clock
cycle; otherwise, this reset signal might not be recognized. This
timing reset applies to the HD timing counters only.
Because the field counter is not reset, it is
recommended that the reset signal is applied in Field 7
(PAL) or Field 3 (NTSC). The reset of the phase will
then occur on the next field, i.e., Field 1, lined up
correctly with the internal counters. The field count
register at Address 0x7B can be used to identify the
number of active fields.
SD REAL-TIME CONTROL, SUBCARRIER RESET,
AND TIMING RESET
[Subaddress 0x44, Bit 2 and Bit 1]
Together with the RTC_SCR_TR pin and SD Mode Register 3
[Address 0x44, Bit 1 and Bit 2], the ADV7324 can be used in
(a) timing reset mode, (b) subcarrier phase reset mode, or
(c) RTC mode.
c. In RTC mode, the ADV7324 can be used to lock to an
external video source. The real-time control mode
allows the ADV7324 to automatically alter the
subcarrier frequency to compensate for line length
variations. When the part is connected to a device,
such as an ADV7402A video decoder (see Figure 61),
that outputs a digital data stream in RTC format, it
automatically changes to the compensated subcarrier
frequency on a line-by-line basis. This digital data
stream is 67 bits wide, and the subcarrier is contained
in Bit 0 to Bit 21. Each bit is two clock cycles long.
Write 0x00 into all four subcarrier frequency registers
when this mode is used.
a. A timing reset is achieved after a low-to-high
transition on the RTC_SCR_TR pin (Pin 31). In this
state, the horizontal and vertical counters remain
reset. Upon releasing this pin (set to low), the internal
counters resume counting, starting with Field 1, and
the subcarrier phase is reset.
The minimum time the pin must be held high is one
clock cycle; otherwise, this reset signal might not be
recognized. This timing reset applies to the SD timing
counters only.

In fast forward mode, the sync information at the start of a new
field in the incoming video usually occurs before the correct
number of lines/fields are reached; in rewind mode, this sync
signal usually occurs after the total number of lines/fields are
reached. Conventionally, this means that the output video will
have corrupted field signals, because one signal is generated by
the incoming video and another is generated when the internal
lines/field counters reach the end of a field.

A reset is activated with a high-to-low transition on the

SUBCARRIER FREQUENCY REGISTERS
The ADV7324 accepts input data that contains VBI data (such
as CGMS, WSS, VITS) in SD and HD modes.
[Subaddresses 0x4C to 0x4F]
Four 8-bit registers are used to set up the subcarrier frequency.
The value of these registers is calculated using the equation
For the SMPTE 293M (525p) standard, VBI data can be
inserted on Line 13 to Line 42 of each frame, or on Line 6 to
Line 43 for the ITU-R BT.1358 (625p) standard.
Subcarrier Frequency Register =
Number of subcarrier periods in one video line

This data can be present on Line 10 to Line 20 for SD NTSC
and on Line 7 to Line 22 for PAL.

where the sum is rounded to the nearest integer.
For example, in NTSC mode
If VBI is disabled [Address 0x11, Bit 4 for HD; Address 0x43,
Bit 4 for SD], VBI data is not present at the output, and the
entire VBI is blanked. These control bits are valid in all master
and slave modes.

Bit 3] must be enabled to allow VBI data to pass through the
ADV7324. Otherwise, the ADV7324 automatically blanks the
VBI to standard.
See the MPU Port Description section for more details on
accessing the subcarrier frequency registers.
If CGMS is enabled and VBI is disabled, the CGMS data will
nevertheless be available at the output.
Programming the FSC
See Appendix 1—Copy Generation Management System.
The subcarrier register value is divided into four FSC registers, as
shown above. To load the value into the encoder, users must
write to the FSC registers in sequence, starting with FSC0. The
value is not loaded until the FSC4 write is complete.
Note that the ADV7324 power-up value for FSC0 is 0x1E. For
precise NTSC FSC, write 0x1F to this register.

shown in Figure 32 and Figure 33.
1 Pass-band ripple is the maximum fluctuation from the 0 dB response in the
pass band. The pass band is defined to have 0 Hz to fc (Hz) frequency limits
for a low-pass filter, and 0 Hz to f1 (Hz) and f2 (Hz) to infinity for a notch filter,
where fc, f1, and f2 are the −3 dB points.
2 3 dB bandwidth refers to the −3 dB cutoff frequency.
In addition to the chroma filters listed in Table 27, the
ADV7324 contains an SSAF filter specifically designed for the
color difference component outputs, U and V. This filter has a
cutoff frequency of about 2.7 MHz and a gain of –40 dB at
3.8 MHz, as shown in Figure 65. This filter can be controlled
with Address 0x42, Bit 0.

Manual RGB Matrix Adjust Feature
COLOR CONTROLS AND RGB MATRIX
Normally, there is no need to enable this feature in Register 0x02,
Bit 3, because the RGB matrix automatically performs color
space conversion depending on the input mode chosen (SD/PS,
HD) and the polarity of RGB/YPrPb output in Register 0x02,
Bit 5 (see Table 30). For this reason, the manual RGB matrix
adjust feature is disabled by default. However, For HDTV
YCrCb-to-RGB conversion, the RGB matrix must be enabled to
invoke the correct coefficients for this color space. The
coefficients do not need to be adjusted.
HD Y Level, HD Cr Level, HD Cb Level
[Subaddresses 0x16 to 0x18]
Three 8-bit registers at Address 0x16, Address 0x17, and
Address 0x18 are used to program the output color of the
internal HD test pattern generator, be it the lines of the cross
hatch pattern or the uniform field test pattern. They are not
functional as color controls for external pixel data input. For
this purpose, the RGB matrix is used.
The manual RGB matrix adjust feature provides custom
coefficient manipulation and is used in PS and HD modes only.
The values for Y and the color difference signals used to obtain
white, black, and saturated primary and complementary colors
conform to the ITU-R BT.601-4 standard.
Rev. 0 | Page 49 of 92
ADV7324
When the manual RGB matrix adjust feature is enabled, the
default values in Registers 0x05 to 0x09 are correct for HDTV
color space only. The color components are converted
according to the 1080i and 720p standards (SMPTE 274M,
SMPTE 296M):
If RGB output is selected, the RGB matrix scaler uses the
following equations:
G = GY × Y + GU × Pb + GV × Pr
B = GY × Y + BU × Pb
R = Y + 1.575Pr
R = GY × Y + RV × Pr
G = Y − 0.468Pr − 0.187Pb
B = Y + 1.855Pb
If YPrPb output is selected, the following equations are used:
Y = GY × Y
U = BU × Pb
V = RV × Pr
This is reflected in the preprogrammed values GY = 0x13B,
GU = 0x3B, GV = 0x93, BU = 0x248, and RV = 0x1F0.
If the RGB matrix is enabled and another input standard (such
as SD or PS) is used, the scale values for GY, GU, GV, BU, and
RV must be adjusted according to this input standard color
space. The user should consider that the color component
conversion might use different scale values. For example,
SMPTE 293M uses the following equations for conversion:
Upon power-up, the RGB matrix is programmed with the
default values listed in Table 31.

The manual RGB matrix adjust feature can be used to control
the HD output levels in cases where the video output does not
conform to the standard due to altering the DAC output stages
such as termination resistors. The programmable RGB matrix is
used for external HD/PS data and is not functional when internal
test patterns are enabled. To adjust Registers 0x05 to 0x09, the
manual RGB matrix adjust must be enabled [Register 0x02,
Bit 3 = 1].
When the manual RGB matrix adjust feature is not enabled, the
ADV7324 automatically scales YCrCb inputs to all standards
supported by this part, as selected by the input mode,
Register 0x01 [6:4].
SD Luma and Color Control
[Subaddresses 0x5C, 0x5D, 0x5E, 0x5F]
Programming the RGB Matrix
SD Y Scale, SD Cr Scale, and SD Cb Scale are three 10-bit-wide
control registers that scale the Y, Cb, and Cr output levels.
If custom manipulation of coefficients is required, enable the
RGB matrix in Address 0x02, Bit 3, set the output to RGB
[Address 0x02, Bit 5], and disable sync on PrPb (default)
[Address 0x15, Bit 2]. Enabling sync on RGB is optional
[Address 0x02, Bit 4].
Each of these registers represents the value required to scale the
Cb or Cr level from 0.0 to 2.0 and the Y level from 0.0 to 1.5 of
its initial level. The value of these 10 bits is calculated using the
following equation:
GY at Address 0x03 and Address 0x05 controls the green signal
output levels. BU at Address 0x04 and Address 0x08 controls
the blue signal output levels, and RV at Address 0x04 and
Address 0x09 controls the red signal output levels. To control
YPrPb output levels, enable the YUV output [Address 0x02, Bit 5].
In this case, GY [Address 0x05; Address 0x03, Bit 0 and Bit 1] is
used for the Y output, RV [Address 0x09; Address 0x04, Bit 0
and Bit 1] is used for the Pr output, and BU [Address 0x08;
Address 0x04, Bit 2 and Bit 3] is used for the Pb output.
Y, Cr, or Cb Scalar Value = Scale Factor × 512
For example,
Scale Factor = 1.18
Y, Cb, or Cr Scale Value = 1.18 × 512 = 665.6

SD Brightness Control
[Subaddress 0x61]
The brightness is controlled by adding a programmable setup
level onto the scaled Y data. This brightness level may be added
onto the scaled Y data. For NTSC with pedestal, the setup can
vary from 0 IRE to 22.5 IRE. For NTSC without pedestal and
for PAL, the setup can vary from −7.5 IRE to +15 IRE.
Note that this feature affects all interlaced output signals, i.e.,
CVBS, Y-C, YPrPb, and RGB.
SD Hue Adjust Value
[Subaddress 0x60]
The brightness control register is an 8-bit register. Seven bits of
this 8-bit register are used to control the brightness level, which
can be a positive or negative value.
The hue adjust value is used to adjust the hue on the composite
and chroma outputs.
For example,
These eight bits represent the value required to vary the hue of
the video data, i.e., the variance in phase of the subcarrier
during active video with respect to the phase of the subcarrier
during the color burst. The ADV7324 provides a range of
22.5° increments of 0.17578125°. For normal operation (zero
adjustment), this register is set to 0x80. Values 0xFF and 0x00
represent the upper and lower limits, respectively, of attainable
adjustment.
1. To add +20 IRE brightness level to an NTSC signal with
pedestal, write 0x28 to Address 0x61, SD brightness.
0x[SD Brightness Value] =
0x[IRE Value × 2.015631] =
0x[20 × 2.015631] = 0x[40.31262] = 0x28
Hue Adjust (°) = 0.17578125° (HCRd − 128) for positive hue
adjust value.
2. To add –7 IRE brightness level to a PAL signal, write 0x72 to
Address 0x61, SD brightness.
For example, to adjust the hue by +4°, write 0x97 to the hue
adjust value register:
[IRE Value| × 2.075631

[Subaddress 0x13, Bit 7; Subaddress 0x48, Bit 2]
Double-buffered registers are updated once per field upon the
falling edge of the Vsync signal. Double buffering improves the
overall performance, because modifications to register settings
will not be made during active video, but take effect upon the
start of the active video.

GAMMA CORRECTION
[Subaddresses 0x24 to 0x37 for HD,
Subaddresses 0x66 to 0x79 for SD]
Gamma correction is available for SD and HD video. For each
standard, there are twenty 8-bit-wide registers. They are used to
program Gamma Correction Curve A and Gamma Correction
Curve B. HD Gamma Curve A is programmed at Address 0x24
to Address 0x2D, and HD Gamma Curve B is programmed at
Address 0x2E to Address 0x37. SD Gamma Curve A is
300mV
Figure 69. Programmable DAC Gain—Positive and Negative Gain
programmed at Address 0x66 to Address 0x6F, and SD Gamma
Curve B is programmed at Address 0x70 to Address 0x79.
In Case A, the video output signal is gained. The absolute level
of the sync tip and blanking level both increase with respect to
the reference video output signal. The overall gain of the signal
is increased from the reference signal.
Generally gamma correction is applied to compensate for the
nonlinear relationship between signal input and brightness level
output (as perceived on the CRT). It can also be applied
wherever nonlinear processing is used.
In Case B, the video output signal is reduced. The absolute level
of the sync tip and blanking level both decrease with respect to
the reference video output signal. The overall gain of the signal
is reduced from the reference signal.
Gamma correction uses the function
γ

)
The range of this feature is specified for 7.5% of the nominal
output from the DACs. For example, if the output current of the
DAC is 4.33 mA, the DAC tune feature can change this output
current from 4.008 mA (−7.5%) to 4.658 mA (+7.5%).
where γ = gamma power factor.
Gamma correction is performed on the luma data only. The
user may choose either of two curves: Curve A or Curve B. At
any one time, only one of these curves can be used.
The reset value of the vid_out_ctrl registers is 0x00; therefore,
nominal DAC current is output. Table 33 is an example of how
the output current of the DACs varies for a nominal 4.33 mA
output current.
The response of the curve is programmed at 10 predefined
locations. By changing the values at these locations, the gamma
curve can be modified. Between these points, linear interpolation
is used to generate intermediate values. If the curve has a total
length of 256 points, the 10 locations are at 24, 32, 48, 64, 80, 96,
128, 160, 192, and 224. Locations 0, 16, 240, and 255 are fixed
and cannot be changed.

There are three filter modes available on the ADV7324: a
sharpness filter mode and two adaptive filter modes.
The edges can then be attenuated with the settings in HD
Adaptive Filter Gain 1, HD Adaptive Filter Gain 2, HD Adaptive
Filter Gain 3 registers, and HD sharpness filter gain register.
HD Sharpness Filter Mode
To enhance or attenuate the Y signal in the frequency ranges
shown in Figure 72, the HD sharpness filter must be enabled,
and the HD adaptive filter enable must be disabled.
According to the settings of the HD adaptive filter mode
control, there are two adaptive filter modes available:
To select one of the 256 individual responses, the corresponding
gain values, which range from –8 to +7, for each filter must be
programmed into the HD sharpness filter gain register at
Address 0x20.
•
Mode A is used when adaptive filter mode is set to 0. In
this case, Filter B (LPF) will be used in the adaptive filter
block. Also, only the programmed values for Gain B in the
HD sharpness filter gain and HD Adaptive Filter Gain 1,
HD Adaptive Filter Gain 2, and HD Adaptive Filter Gain 3
are applied when needed. The Gain A values are fixed and
cannot be changed.
HD Adaptive Filter Mode
The HD Adaptive Filter Threshold A, HD Adaptive Filter
Threshold B, and HD Adaptive Filter Threshold C registers; the
HD Adaptive Filter Gain 1, HD Adaptive Filter Gain 2, and HD

register are used in adaptive filter mode. To activate the
adaptive filter control, the HD sharpness filter and the HD
adaptive filter must be enabled.
•
Mode B is used when adaptive filter mode is set to 1. In
this mode, a cascade of Filter A and Filter B is used.
Settings for Gain A and Gain B in the HD sharpness filter

[Address 0x15, Bit 6], the output shown in Figure 76 can be

SD DIGITAL NOISE REDUCTION
[Subaddresses 0x63, 0x64, 0x65]
DNR is applied to the Y data only. A filter block selects the high
frequency, low amplitude components of the incoming signal
(DNR input select). The absolute value of the filter output is
compared to a programmable threshold value (DNR threshold
control). There are two DNR modes available: DNR mode and
DNR sharpness mode.
In DNR mode, if the absolute value of the filter output is less
than the threshold, it is assumed to be noise. A programmable
amount (coring gain border, coring gain data) of this noise
signal will be subtracted from the original signal. Likewise, in
DNR sharpness mode, if the absolute value of the filter output is
less than the programmed threshold, it is assumed to be noise.
If the level exceeds the threshold and is identified as a valid
signal, a fraction of the signal (coring gain border, coring gain
data) will be added to the original signal to boost high

In MPEG systems, it is common to process the video
information in blocks of 8 pixels × 8 pixels for MPEG2 systems,
or 16 pixels × 16 pixels for MPEG1 systems (block size control).
DNR can be applied to the resulting block transition areas that
are known to contain noise. Generally, the block transition area
contains two pixels. It is possible to define this area to contain
four pixels (border area).
It is also possible to compensate for variable block positioning
or differences in YCrCb pixel timing with the use of the DNR
block offset.
The digital noise reduction registers are three 8-bit registers.
They are used to control the DNR processing.

This bit is used to select the size of the data blocks to be

When the active video edge feature is enabled, the first three

channel are scaled so that maximum transitions on these pixels
are not possible. The scaling factors are ×1/8, ×1/2, and ×7/8.
All other active video passes through unprocessed.
DNR MODE CONTROL
[Address 0x65, Bit 4]
This bit is used to select the DNR mode. Logic 0 selects DNR
mode; Logic 1 selects DNR sharpness mode.
SAV/EAV STEP-EDGE CONTROL
DNR works on the principle of defining low amplitude, high
frequency signals as probable noise and subtracting this noise
from the original signal.
The ADV7324 has the capability of controlling fast rising and
falling signals at the start and end of active video to minimize
ringing.
In DNR mode, it is possible to subtract a fraction of the signal
that lies below the set threshold, assumed to be noise, from the
original signal. The threshold is set in DNR Register 1.
An algorithm monitors SAV and EAV and determines when the
edges are rising or falling too fast. The result is reduced ringing
at the start and end of active video for fast transitions.
Subaddress 0x42, Bit 7 = 1, enables this feature.
When DNR sharpness mode is enabled, it is possible to add a
fraction of the signal that lies above the set threshold to the
original signal, since this data is assumed to be valid data and

DAC output traces on a PCB should be treated as transmission
lines. It is recommended that the DACs be placed as close as
possible to the output connector, with the analog output traces
being as short as possible (less than 3 inches). The DAC termi-
nation resistors should be placed as close as possible to the DAC
outputs and should overlay the PCB’s ground plane. As well as
minimizing reflections, short analog output traces reduce noise
pickup from neighboring digital circuitry.

Optimum performance is achieved by the use of 10 nF and
0.1 µF ceramic capacitors. Each group of VAA, VDD, or VDD_IO
pins should be individually decoupled to ground. This should
be done by placing the capacitors as close as possible to the
device with the capacitor leads as short as possible, thus
minimizing lead inductance.

PCB BOARD LAYOUT
A 1 µF tantalum capacitor is recommended across the VAA
supply in addition to 10 nF ceramic. See the circuit layout in
Figure 90.
The ADV7324 is optimally designed for lowest noise
performance of both radiated and conducted noise. To
complement the excellent noise performance of the ADV7324,
it is imperative that great care be given to the PC board layout.
Digital Signal Interconnect
The digital signal lines should be isolated as much as possible
from the analog outputs and other analog circuitry. Digital
signal lines should not overlay the analog power plane.
The layout should be optimized for lowest noise on the
ADV7324 power and ground lines. This can be achieved by
shielding the digital inputs and providing good decoupling. The
lead length between groups of VAA and AGND, VDD and DGND,
and VDD_IO and GND_IO pins should be kept as short as
possible to minimized inductive ringing.
Due to the high clock rates, avoid long clock lines to the
ADV7324 to minimize noise pickup.
Any active pull-up termination resistors for the digital inputs
should be connected to the digital power plane, not the analog
power plane.
It is recommended that a 4-layer, printed circuit board is used,
with power and ground planes separating the layer of the signal
carrying traces of the components and solder side layer. Com-
ponent placement should be carefully considered to separate
noisy circuits, such as crystal clocks, high speed logic circuitry,
and analog circuitry.
Analog Signal Interconnect
Locate the ADV7324 as close as possible to the output
connectors to minimize noise pickup and reflections due to
impedance mismatch.
Rev. 0 | Page 63 of 92
ADV7324
For optimum performance, each analog output should be
source- and load-terminated, as shown in Figure 90. The
termination resistors should be as close as possible to the
ADV7324 to minimize reflections.
For optimum performance, it is recommended that all
decoupling and external components relating to the ADV7324
are located on the same side of the PCB and as close as possible
to the ADV7324. Unused inputs should be tied to ground.

SD CGMS
Data Registers 2 to 0
[Subaddresses 0x21, 0x22, 0x23]
[Subaddresses 0x59, 0x5A, 0x5B]
The ADV7324 supports the copy generation management
system (CGMS), conforming to the EIAJ CPR-1204 and
ARIB TR-B15 standards. CGMS data is transmitted on Line 20
of the odd fields and Line 283 of the even fields. Bit C/W05 and
Bit C/W06 control whether CGMS data is output on odd or
even fields. CGMS data can only be transmitted when the
ADV7324 is configured in NTSC mode. The CGMS data is
20 bits long. The CGMS data is preceded by a reference pulse of
the same amplitude and duration as a CGMS bit; see Figure 93.
525p
Using the vertical blanking interval 525p system, 525p CGMS
conforms to the CGMS-A EIA-J CPR1204-1 (March 1998)
transfer method of video identification information and to the
IEC61880 (1998) 525p/60 video system’s analog interface for the
video and accompanying data.
When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS
data is inserted on Line 41. The 525p CGMS data registers are at
Address 0x21, Address 0x22, and Address 0x23.
720p System
CGMS data is applied to Line 24 of the luminance vertical
blanking interval.
625p
The 625p CGMS conforms to the IEC62375 (2004) 625p/50
video system’s analog interface for the video and accompanying
data using the vertical blanking interval.
1080i System
CGMS data is applied to Line 19 and Line 582 of the luminance
vertical blanking interval.
When PS CGMS is enabled [Subaddress 0x12, Bit 6 = 1], CGMS
data is inserted on Line 43. The 625p CGMS data registers are at
Address 0x22 and Address 0x23.
CGMS FUNCTIONALITY
If SD CGMS CRC [Address 0x59, Bit 4] or PS/HD CGMS CRC
[Subaddress 0x12, Bit 7] is set to Logic 1, the last six bits, C19 to
C14, which compose the 6-bit CRC check sequence, are
automatically calculated on the ADV7324. This calculation is
based on the lower 14 bits (C0 to C13) of the data in the data
registers and output with the remaining 14 bits to form the
complete 20 bits of the CGMS data. The calculation of the CRC
sequence is based on the polynomial x6 + x + 1 with a preset
value of 111111. If SD CGMS CRC [Address 0x59, Bit 4] and
PS/HD CGMS CRC [Address 0x12, Bit 7] are set to Logic 0, all
20 bits (C0 to C19) are output directly from the CGMS registers
(CRC must be manually calculated by the user).
HD CGMS
[Address 0x12, Bit 6]
The ADV7324 supports the copy generation management
system (CGMS) in HDTV mode (720p and 1080i) in
accordance with EIAJ CPR-1204-2.
The HD CGMS data registers are found at Address 0x021,
Address 0x22, and Address 0x23.

APPENDIX 3—SD CLOSED CAPTIONING
[Subaddresses 0x51 to 0x54]
FCC Code of Federal Regulations (CFR) 47, section 15.119, and
EIA608 describe the closed captioning information for Line 21
and Line 284.
The ADV7324 supports closed captioning conforming to the
standard television synchronizing waveform for color
transmission. Closed captioning is transmitted during the
blanked active line time of Line 21 of the odd fields and
Line 284 of the even fields.
The ADV7324 uses a single-buffering method. This means that
the closed captioning buffer is only 1 byte deep; therefore, there
will be no frame delay in outputting the closed captioning data,
unlike other 2-byte-deep buffering systems. The data must be
loaded one line before it is output on Line 21 and Line 284. A
Closed captioning consists of a 7-cycle sinusoidal burst that is
frequency- and phase-locked to the caption data. After the
clock run-in signal, the blanking level is held for two data bits
and is followed by a Logic 1 start bit. Sixteen bits of data follow
the start bit. These consist of two 8-bit bytes, seven data bits,
and one odd parity bit. The data for these bytes is stored in the
SD closed captioning registers [Address 0x53 to Address 0x54].
typical implementation of this method is to use
to inter-
VSYNC
rupt a microprocessor, which in turn will load the new data
(2 bytes) in every field. If no new data is required for transmission,
0s must be inserted in both data registers; this is called nulling.
It is also important to load control codes, all of which are double
bytes, on Line 21, or a TV will not recognize them. If there is a
message such as “Hello World” that has an odd number of char-
acters, it is important to add a blank character at the end so that
the end-of-caption, 2-byte control code lands in the same field.
The ADV7324 also supports the extended closed captioning
operation, which is active during even fields and encoded on
Line 284. The data for this operation is stored in the SD closed
captioning registers [Address 0x51 to Address 0x52].
All clock run-in signals and timing to support closed captioning
on Line 21 and Line 284 are generated automatically by the
ADV7324. All pixels inputs are ignored during Line 21 and
Line 284 if closed captioning is enabled.

APPENDIX 5—SD TIMING MODES
[Subaddress 0x4A]
MODE 0 (CCIR-656)—SLAVE OPTION
(TIMING REGISTER 0 TR0 = X X X X X 0 0 0)
The ADV7324 is controlled by the SAV (start active video) and
EAV (end active video) time codes in the pixel data. All timing
information is transmitted using a 4-byte synchronization pattern.
A synchronization pattern is sent immediately before and after
each line during active picture and retrace. If Pin
,
S_VSYNC
Pin
, and Pin
S_BLANK
are not used, they should be
S_HSYNC
tied high during this mode. Blank output is available.
