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.
