ADI ADV473KP80

The device consists of three, high speed, 8-bit, video D/A converters (RGB), a 256×24 RAM which can be configured as a look-up table or a linearization RAM, a 24-bit wide parallel pixel input port and three 15×8 overlay registers. The part is controlled through the MPU port by the various on-board control/command registers. The individual red, green and blue pixel input ports allow true color, image rendition. True-color image rendition, at speeds of up to 135 MHz is achieved through the 24-bit pixel input port. The ADV473 is also capable of implementing 8-bit true color, 8-bit pseudocolor and 15-bit true color. The ADV473 is capable of generating RGB video output signals, without requiring external buffering, and which are compatible with RS-343A and RS-170 video standards. All digital inputs and outputs are TTL compatible. The part can be driven by the on-board voltage reference or an external voltage reference. The part is packaged in a 68-pin Plastic Leaded Chip Carrier (PLCC).
