description
The TVP3703 is a super video graphics array (SVGA) compatible, true-color CMOS RAMDAC with integrated
clock synthesizers that can provide the memory and pixel clock signals for a PC graphics subsystem. The video
clock can be one of two VGA base frequencies or fourteen Video Electronics Standards Association (VESA)
standard frequencies which can also be reprogrammed through the standard micro port interface.
The memory clock output is also user programmable at frequencies up to 80 MHz. The pixel modes supported
by the TVP3703 include:
•
Serializing 16-bit pixel port providing 170 MHz, 8-bit and 73 MHz, 24-bit packed pixel modes using an
internal PLL
•
•
16-bit pixel port providing faster, high-color/true-color operation up to the 110 MHz sampling rate
8-bit pixel port providing standard SVGA and high-color/true-color modes up to the 110 MHz sampling rate
The 68 terminal FN package is designed to be interchangeable with the STG1703.

detailed description
micro port
The TVP3703 micro port (see Table 1) is an extension of the standard VGA micro port and powers up with a
register configuration compatible with standard and high-color VGA. There are two methods for accessing the
register set of the TVP3703 – direct register space (RS) access and indirect access.
direct RS access
This feature supports direct RS mapping to eight address locations that access the VGA color palette, pixel
command register, and an indexed register. The index low/high registers increment after every access to the
indexed register.

indirect access
The indexed register space can also be accessed by a special mechanism of successive reads to the mask
register location 2h, as shown in Table 2. Reads from RS location 2h cause a state counter to be advanced by
one. Five successive reads of RS location 2h returns the mask register contents four times followed by the pixel
command register value.
If the indexed register space is not enabled, the next access is directed to the pixel mask (state 1 in Table 2).
States 3 to 4 require three reads from the pixel mask register and, when the pixel command register is written
to enable the indexed register space, the next access is again directed to the mask register (the next state after
state 5 is state 1).
The indirect access sequence can now enter states 6 and 7 to access the lower and higher byte of the index
register respectively. Subsequent reads or writes to location 2h access the register space pointed to by the index
register. After each indexed register access, the index register increments automatically. In this way, the entire
indexed register space can be moved as a block without the need to keep writing to the index register.
At any point in the above sequence, a read or write to any location other than 2h resets the state counter to
state 1.
On power up, the indirect access is truncated through the default setting of pixel command register bit 4 so that
the TVP3703 is identified by existing video basic input/output system (BIOS) code as a fast ATT20C490
RAMDAC.

power management features
Two power reduction options are available on the TVP3703.
1. Bit 0 of the pixel command register (sleep mode) provides a default power-down mode in which the following
sections of the device are powered down:
•
•
•
•
All pixel multiplexor modes
All post-RAM logic
The triple DAC
The mask logic
Micro port and palette-RAM power is maintained to allow read and write access to the internal registers or

use of the hardware CRC feature
The TVP3703 hardware CRC feature supports testing of the entire pixel data path from the pixel port through
to the DAC inputs at full video rates up to 170 MHz on the TVP3703. Each of the three colors (red, green and
blue) are tested independently. CRCs are accumulated during active display, with accumulation being gated by
the BLANK signal.
A TVP3703 CRC can be accumulated in either active screen or self-test-pattern generation mode and is
controlled by bit 1 of the CRC test register (index FFD6h). To use the pattern generated CRC feature, perform
the following test procedure:
1. Set the mode and verify the PIXMIX signal is low.
2. Set the proper values in the CRC test register for the desired CRC mode. Set BLANK low. Wait for ten
PCLKS cycles.
3. Set bit 2 of the CRC test register to 1 and bit 1 to 0.

The CRC technique allows an authoritative check to be performed between the intended display and the actual
display at full video rates. For a given image (which can be an application’s image or a specially prepared test
screen), theoretically derived CRC values are calculated for each RGB color, which are then compared with the
TVP3703 hardware CRC values. Alternatively, the CRC value from a known good screen can be used as the
reference.
The CRC facility on the TVP3703 can be used to validate correct operation of:
•
•
•
•
•
The TVP3703 device in isolation
The TVP3703 device designed into, and working in, a VGA board
The DRAM, controller, and data path on the VGA board
The disk and bus operation of the host PC
MS-Windows (and device drivers) on the PC
The horizontal and vertical synchronization waveforms or timings do not affect hardware CRC accumulation.
Any discrepancy between the calculated and TVP3703 hardware accumulated CRC values indicates a problem
in the device or system being used.
The CRC logic on the TVP3703 is normally powered down. To perform a CRC test, bit 2 of the CRC test register
(index FFD6h) should be reset to 0 and returned to 1 afterwards to return to the default condition.
The CRC mechanism does not check the DAC outputs (i.e., what is physically being displayed on the monitor);
these can be tested using the TVP3703 SENSE output (generally readable as a register bit on the VGA
controller).

The rising edge of PCLK latches all of the pixels. Modes requiring more than one word per pixel accumulate
the least significant bytes of the pixel first. BLANK going high always identifies the first word within a pixel. The
VGA, SVGA, and extended pixel modes are listed in Tables 5 and 6.

Modes 5 (05h) and 9 (09h) use PLL, DAC CLK = 2 × PCLK or 2/3 PCLK respectively.
primary and secondary pixel mode combinations
Writing to the pixel command register enables the extended pixel modes. A primary pixel mode and a secondary
pixel mode are defined for the TVP3703. The TVP3703 switches between these two modes on the fly under
control of the PIXMIX terminal.
The PIXMIX terminal and the pixel terminals are sampled on PCLK. If the primary or secondary pixel mode
format requires two PCLK edges to build a whole pixel, then PIXMIX should only change state on every second
PCLK edge after BLANK has gone high at the start of a line.
When PIXMIX is not in use, the primary and secondary pixel mode select registers should be written with the
same value.
The primary and secondary pixel mode combinations are listed in Table 7.

NOTE 2: Pixel switching can only be performed when the PCLK to dot clock ratios for the
primary and secondary modes are the same.
programming of pixel modes using the PLL
The TVP3703 uses an internal PLL to generate the internal dot clock. This PLL automatically adjusts the PCLK
to dot clock ratio based on the multiplexing mode selected. Therefore no further programming is necessary.
pixel resolution and blanking periods in mode 09h
In mode 09h (packed 24-bit), latching 16 bits of data from 3 PCLK cycles generates a group of 2 pixels. This
means that the horizontal screen resolution must be an even number of pixels, and the number of PCLK cycles
during active display must be a multiple of 3.
Due to the internal phase relationships between PCLK and the pixel clock generated by the internal PLL, the
horizontal and vertical blanking period must also be an integral multiple of 3 PCLK cycles. This must be satisfied
so that the first pixel of each line always appears at the same point horizontally on the screen, from line to line
and from frame to frame.
Therefore mode 09h requires the following relationships must be satisfied:
Horizontally:
The total horizontal duration must be an integral multiple of 3 PCLKs.
HTOT
i.e.,
integer, where HTOT
total horizontal duration in standard VGA registers.
3
Vertically:
The total vertical duration must be an integral multiple of 3 PCLKs.
VTOT HTOT
i.e.,
integer, where VTOT
total vertical duration in standard VGA registers.
3
In all standard VGA systems, if the horizontal requirement is met, the vertical requirement is also met.
VGA standard controllers normally satisfy the requirements described in this section because the horizontal
blanking period is specified in character widths (8 pixels wide), vertical blanking in terms of scan lines, and
resolution in even pixels.
