ADV7129
GENERAL DESCRIPTION
The ADV7129 is a complete analog output, video DAC on a single
CMOS (ADV®) monolithic chip. The part is specifically designed
for use in the highest resolution graphics and imaging systems.
The ultimate level of integration, comprised of 360 MHz triple
8-bit DACs, a programmable pixel port, an internal voltage reference and an onboard PLL, makes the ADV7129 the only choice
for the very highest level of performance and functionality.
The device consists of three high speed, 8-bit, video D/A converters (RGB). An onboard phase locked loop clock generator
is provided to provide high speed operation without requiring
high speed external crystal or clock circuitry.
The part is fully controlled through the MPU port by the onboard command registers. This MPU port may be updated at
any time without causing sparkle effects on the screen.

Static performance is measured with the Gain Error Registers set to 00H (disabled).
4
IAA is measured with a typical dynamic pattern, satisfying the absolute maximum current spec for the DACs.
5
Clock and Data Feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. Glitch impulse includes clock and data
feedthrough. TTL input values are 0 V to 3 V, with input rise/fall times ≥3 ns, measured at the 10% and 90% points. Timing reference points are at 50% for
inputs and outputs.
6
DAC to DAC crosstalk is measured by holding one DAC high while the other two DACs are making low to high and high to low transitions.

Pixel Port consists of the following inputs: Pixel Inputs: RED [A-H], BLUE [A-H], GREEN [A-H].
5
Output Delay is measured from the 50% rising edge of LOADIN to the 50% point of full-scale transition on the A pixel. t17 includes the analog delay due to DACs
and internal gate transitions plus the pipeline stages delay. The output delay for pixels B-H will be the output delay to the A pixel (t17) plus the appropriate number
of clock cycles. Output rise/fall time is measured between the 10% and 90% points of full-scale transition. Settling time is measured from the 50% point of full-scale
transition to the output remaining within 1%. (Settling Time does not include clock and data feedthrough.)
6
Jitter is measured by triggering on the output clock, delayed by 15 µs and then measuring the time period from the trigger edge to the next edge of the output clock
after the delay. This measurement is repeated multiple times and the rms value is determined.

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 the ADV7129 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.
