The part is specifically designed for use in high performance, color graphics workstations. The ADV7152 integrates a number of graphic functions onto one device allowing 24-bit direct True-Color operation at the maximum screen update rate of 220 MHz. The ADV7152 implements 30-bit True Color in 24-bit frame buffer designs. The part also supports other modes, including 15-bit True Color and 8-bit Pseudo or Indexed Color. Either the Red, Green or Blue input pixel ports can be used for Pseudo Color. The device consists of three, high speed, 10-bit, video D/A converters (RGB), three 256 ϫ 10 (one 256 ϫ 30) color look-up tables, pal...
