GENERAL D ESCRIP TIO N

T he ADV7150 (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 ADV7150 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

ADV7150 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.
