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 refer-
ence 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 con-
verters (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 on-
board command registers. This MPU port may be updated at
any time without causing sparkle effects on the screen.

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.
