ADI ADV7151LS135

The ADV7151 is a complete analog output, Video RAM-DAC on a single CMOS monolithic chip. The part is specifically designed for use in high performance, color graphics workstations. The ADV7151 integrates a number of graphic functions onto one device allowing 8-bit Pseudo-Color (IndexedColor) operation at the maximum screen update rate of 220 MHz. The device consists of three, high speed, 10-bit, video D/A converters (RGB), three 256 × 10 (one 256 × 30) color look-up tables, palette priority selects, a pixel input data multiplexer/ serializer and a clock generator/divider circuit. The ADV7151 is capable of 1:1, 2:1 and 4:1 multiplexing. The on-board palette priority select inputs enable multiple palette devices to be connected together for use in multipalette and window applications. The part is controlled and programmed through the microprocessor (MPU) port. The part also contains a number of on-board test registers, associated with self/diagnostic testing of the device.
