The ADV101 is a digital-to-analog video converter on a single monolithic chip. The part is specifically designed for high resolution color graphics and video systems. It consists of three, high speed, 8-bit, video D/A converters (RGB); a standard TTL input interface and high impedance, analog output, current sources. The ADV101 has three separate, 8-bit, pixel input ports, one each for red, green and blue video data. Additional video input controls on the part include sync, blank and reference white. A single +5 V supply, an external 1.23 V reference and pixel clock input are all that are required to make the part operational. The ADV101 is capable of generating RGB video output signals, which are compatible with RS……
