Video Decoder and RGB Graphics Digitizer
ADV7401
FEATURES
GENERAL DESCRIPTION
Four 10-bit ADCs sampling up to 140 MHz
(140 MHz speed grade only)
12 analog input channel mux
SCART fast blank support
Internal antialias filters
NTSC/PAL/SECAM color standards support
525p-/625p-component progressive scan support
720p-/1080i-component HDTV support
Digitizes RGB graphics up to 1280 × 1024 @ 75 Hz (SXGA)
(140 MHz speed grade only)
24-bit digital input port supports data from DVI/HDMI Rx IC
Any-to-any, 3 × 3 color-space conversion matrix
Industrial temperature range (−40°C to +85°C)
12-bit 4:4:4/8-bit 4:2:2 DDR pixel output interface
Programmable interrupt request output pin
VBI data slicer (including teletext)
The ADV7401 is a high quality, single chip, multiformat video
decoder and graphics digitizer. This multiformat decoder
supports the conversion of PAL, NTSC, and SECAM standards
in the form of composite or S-video into a digital ITU-R BT.656
format. The ADV7401 also supports the decoding of a
component RGB/YPrPb video signal into a digital YCrCb or
RGB pixel output stream. The support for component video
includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i,
1250i, and many other HD and SMPTE standards. Graphic
digitization is also supported by the ADV7401; it is capable of
digitizing RGB graphics signals from VGA to SXGA rates and
converting them into a digital RGB or YCrCb pixel output
stream. SCART and overlay functionality are enabled by the
ADV7401’s ability to simultaneously process CVBS and
standard definition RGB signals. The mixing of these signals is
controlled by the fast blank pin.
The ADV7401 contains two main processing sections. The first
is the standard definition processor (SDP), which processes all
PAL, NTSC, and SECAM signal types. The second is the
component processor (CP), which processes YPrPb and RGB
component formats, including RGB graphics. For more specific
descriptions of the ADV7401 features, see the Detailed
Functionality and Detailed Description sections.

PACKAGE THERMAL PERFORMANCE
To reduce power consumption when using the part the user is
advised to turn off any unused ADCs .
The junction temperature must always stay below the
maximum junction temperature (TJ MAX) of 125°C. This
equation shows how to calculate the junction temperature:
DGND − 0.3 V to DVDDIO + 0.3 V
AGND − 0.3 V to AVDD + 0.3 V

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.

ADV7401
DETAILED DESCRIPTION
ANALOG FRONT END
The SDP has an IF filter block that compensates for attenuation
in the high frequency luma spectrum due to tuner SAW filter.
The ADV7401 analog front end comprises four 10-bit ADCs
that digitize the analog video signal before applying it to the
SDP or CP (see Table 8 for sampling rates). The analog front
end uses differential channels to each ADC to ensure high
performance in a mixed-signal application.
The SDP has specific luminance and chrominance parameter
control for brightness, contrast, saturation, and hue.
The ADV7401 implements a patented adaptive-digital-line-
length-tracking (ADLLT) algorithm to track varying video
line lengths from sources such as a VCR. ADLLT enables the
ADV7401 to track and decode poor quality video sources
such as VCRs, noisy sources from tuner outputs, VCD players,
and camcorders. The SDP also contains a chroma transient
improvement (CTI) processor. This processor increases the
edge rate on chroma transitions, resulting in a sharper
video image.
The front end also includes a 12-channel input mux that enables
multiple video signals to be applied to the ADV7401. Current
and voltage clamps are positioned in front of each ADC to
ensure that the video signal remains within the range of the
converter. Fine clamping of the video signals is performed
downstream by digital fine clamping in either the CP or SDP.
Optional antialiasing filters are positioned in front of each
ADC. These filters can be used to band-limit standard
definition video signals, removing spurious, out-of-band noise.
The SDP can process a variety of VBI data services, such as
TeleText, closed captioning (CC), wide screen signaling (WSS),
video programming system (VPS), vertical interval time codes
(VITC), copy generation management system (CGMS),
Gemstar 1×/2×, and extended data service (XDS). The
ADV7401 SDP section has a Macrovision 7.1 detection circuit
that allows it to detect Types I, II, and III protection levels. The
decoder is also fully robust to all Macrovision signal inputs.
The ADCs are configured to run in 4× oversampling mode
when decoding composite and S-video inputs; 2× oversampling
is performed for component 525i, 625i, 525p, and 625p sources.
All other video standards are 1× oversampled. Oversampling
the video signals reduces the cost and complexity of external
anti-aliasing filters with the benefit of an increased signal-to-
noise ratio (SNR).
COMPONENT PROCESSOR
The ADV7401 can support simultaneous processing of CVBS
and RGB standard definition signals to enable SCART compat-
ibility and overlay functionality. A combination of CVBS and
RGB inputs can be mixed and output under control of I2C
registers and the fast blank pin.
The CP section is capable of decoding/digitizing a wide range of
component video formats in any color space. Component video
standards supported by the CP are 525i, 625i, 525p, 625p, 720p,
1080i, 1250i, VGA up to SXGA @ 75 Hz (ADV7401KSTZ-140
only), and many other standards not listed here.
Table 8. Maximum ADC Sampling Rates
The CP section of the ADV7401 contains an AGC block.
When no embedded sync is present, the video gain can be set
manually. The AGC section is followed by a digital clamp
circuit that ensures the video signal is clamped to the correct
blanking level. Automatic adjustments within the CP include
gain (contrast) and offset (brightness); manual adjustment
controls are also supported.

STANDARD DEFINITION PROCESSOR (SDP)
A fully programmable, any-to-any, 3 × 3 color space conversion
matrix is placed between the analog front end and the CP
section. This enables YPrPb-to-RGB and RGB-to-YCrCb
conversions. Many other standards of color space can be
implemented using the color space converter.
The SDP section is capable of decoding a large selection of
baseband video signals in composite S-video and YUV formats.
The video standards supported by the SDP include PAL
B/D/I/G/H, PAL60, PAL M, PAL N, NTSC M/J, NTSC 4.43, and
SECAM B/D/G/K/L. The ADV7401 can automatically detect
the video standard and process it accordingly.
The SDP has a 5-line superadaptive 2D comb filter that gives
superior chrominance and luminance separation when decod-
ing a composite video signal. This highly adaptive filter auto-
matically adjusts its processing mode according to video
standard and signal quality with no user intervention required.
Rev. B | Page 15 of 20
ADV7401
The output section of the CP is highly flexible. It can be config-
ured in single data rate mode (SDR) with one data packet per
clock cycle or in a double data rate (DDR) mode where data is
presented on the rising and falling edges of the clock. In SDR
mode, a 16-bit 4:2:2 or 24-bit 4:4:4 output is possible. In these
modes HS, VS, and FIELD/DE (where applicable) timing refer-
ence signals are provided. In DDR mode, the ADV7401 can be
configured in an 8-bit 4:2:2 YCrCb or 12-bit 4:4:4 RGB/ YCrCb
pixel output interface with corresponding timing signals.
The CP section contains circuitry to enable the detection of
Macrovision encoded YPrPb signals for 525i, 625i, 525p, and
625p. It is designed to be fully robust when decoding these
types of signals.
VBI extraction of CGMS data is performed by the CP section
of the ADV7401 for interlaced, progressive, and high definition
scanning rates. The data extracted can be read back over the
I2C interface. For more detailed product information about the
ADV7401, contact your local ADI sales office or email
video.products@analog.com.
The ADV7401 is capable of supporting an external DVI/
HDMI receiver. The digital interface expects 24-bit 4:4:4 or
16-bit 4:2:2 bit data (either graphics RGB or component video
YCrCb), accompanied by HS, VS, DE, and a fully synchronous
clock signal. The data is processed in the CP and output as
16-bit 4:2:2 YCrCb data.
