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.
