T he ADV7120 (ADV
) is a digital to analog video converter on
a single monolithic chip. T he 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 T T L input inter-
face and high impedance, analog output, current sources.
T he 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.
T he 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.
T he ADV7120 is fabricated in a +5 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with low power dissipation. T he part is packaged in both a 0.6",
40-pin plastic DIP and a 44-pin plastic leaded (J-lead) chip car-
rier, PLCC. T he ADV7120 is also available in a very small 48-
lead T hin Quad Flatpack (T QFP).

*Speed grades up to 140 MHz are also available upon special request.
