GENERAL D ESCRIP TIO N

T he ADV7152 (ADV^®) is a complete analog output, Video

RAM-DAC on a single CMOS monolithic chip. T he part is spe-

cifically designed for use in high performance, color graphics

workstations. T he ADV7152 integrates a number of graphic

functions onto one device allowing 24-bit direct T rue-Color op-

eration at the maximum screen update rate of 220 MHz. T he

ADV7152 implements 30-bit T rue Color in 24-bit frame buffer

designs. T he part also supports other modes, including 15-bit

T rue Color and 8-bit Pseudo or Indexed Color. Either the Red,

Green or Blue input pixel ports can be used for Pseudo Color.

Multiplexed Pixel Input Ports; 1:1, 2:1

+5 V CMOS Monolithic Construction

100-Lead Plastic Quad Flatpack (QFP)

T he device consists of three, high speed, 10-bit, video D/A con-

verters (RGB), three 256 ϫ 10 (one 256 ϫ 30) color look-up

tables, palette priority selects, a pixel input data multiplexer/

serializer and a clock generator/divider circuit. T he ADV7152

implements 1:1 and 2:1 pixel data multiplexing. T he onboard

palette priority select inputs enable multiple palette devices to

be connected together for use in multipalette and window
