1 Introduction
The TVP3409 is intended to be a direct replacement for the ATT20C409 RAM digital-to-analog converter
(RAMDAC). The TVP3409 RAMDAC supports 8-bit multiplexed operation that can be input on 16 pixel
terminals. The TVP3409 retains register compatiblity with the ATT20C498 and ATT20C499 devices. The
TVP3409 features 24-bit packed pixel modes that provide 24-bit graphics at up to 1024 x 768 screen
resolution. Dual clock synthesizers offer two programmable and two fixed frequencies in phase-locked-loop
A (PLLA) and one programmable and three fixed frequencies in phase-locked-loop B (PLLB). After reset,
the frequencies are:
PLLA: 25.175, 28.322, 50, and 75 MHz
PLLB: 30, 40, 50, and 60 MHz
Easy identification of the RAMDAC allows the video BIOS to determine if a requested mode is available on
the hardware being used.
