Fast video refresh rate, 80 MHz. The ADV7120 (ADV ) is a digital to analog video converter on a single monolithic chip. The part is specifically designed for 2. Compatible with a wide variety of high resolution color high resolution color graphics and video systems. It is also ideal graphics video systems. for any high speed communications type applications requiring 3. Guaranteed monotonic with a maximum differential non- low cost, high speed DACs. It consists of three, high speed, linearity of 0.5 LSB. Integral nonlinearity is guaranteed to 8-bit, video D/A converters (RGB) a standard TTL input inter- be a maximum of 1 LSB. face 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 refer- ence 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 sig- nals, 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 car- rier, PLCC. The ADV7120 is also available in a very small 48- lead Thin Quad Flatpack (TQFP).
