GENERAL DESCRIPTION The ADV7120 (ADV? ) 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 is also ideal for any high speed communications type applications requiring low cost, high speed DACs. 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 ADV7120 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 composite 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 ADV7120 is capable of generating RGB video output signals, which are compatible with RS-343A and RS-170 video standards, without requiring external buffering. The ADV7120 is fabricated in a +5 V CMOS process. Its monolithic CMOS construction ensures greater functionality with low power dissipation. The part is packaged in both a 0.6", 40-pin plastic DIP and a 44-pin plastic leaded (J-lead) chip carrier, PLCC. The ADV7120 is also available in a very small 48- lead Thin Quad Flatpack (TQFP). ADV is a registered trademark of Analog Devices, Inc. *Speed grades up to 140 MHz are also available upon special request. Please contact Analog Devices or its representatives for further details.
