Cmos Monolithic 256x18 Color Palette Ram-dac - Analog Devices

The ADV476 (ADV) is a pin compatible and software compat- ible RAM-DAC designed specifically for VGA and Personal System/2 color graphics. The ADV476 is a complete Analog output RAM-DAC on a single monolithic chip. The part contains a 256318 color lookup table, a pixel mask Register as well as a triple 6-bit Video D/A Converter The ADV476 is capable of simultaneously dis- playing up to 256 colors, from a total color palette of 262,144 addressable colors. The on-chip asynchronous MPU bus allows access to the color lookup table without affecting the input Video data via the pixel port. The pixel read mask Register provides a convenient way of altering the displayed colors without updating the color lookup table. The ADV476 is capable of generating RGB Video output signals which are compatible with RS-343A and RS-170 Video standards, without requiring external buffering. By Analog Devices, Inc.
