GENERAL DESCRIPTION

The ADV101 is a digital-to-analog video converter on a single

monolithic chip. The part is specifically designed for high reso-

lution 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 sig-

nals, which are compatible with RS-343A and RS-170 video

standards, without requiring external buffering.

The ADV101 is fabricated in a +5 V CMOS process. Its mono-

lithic 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.
