GENERAL DESCRIPTION
The ADV7150 (ADV®) is a complete analog output, Video
RAM-DAC on a single CMOS monolithic chip. The part is spe-
cifically designed for use in high performance, color graphics
workstations. The ADV7150 integrates a number of graphic
functions onto one device allowing 24-bit direct True-Color op-
eration at the maximum screen update rate of 220 MHz. The
ADV7150 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.
