Description

The ADV473 is a complete analog output, Video RAM-DAC on a single CMOS monolithic chip. The part is specifically designed for true-color computer graphics systems.

The ADV473 integrates a number of graphic functions onto one device allowing 24-bit direct true-color operation at the maximum screen update rate of 135 MHz. It can also be used in other modes, including 15-bit true color and 8-bit pseudo or indexed color. It  is fully PS/2 and VGA register level compatible. It is also capable of implementing IBM's XGA standard.
