1. Fast video refresh rate, 80 MHz.
T he ADV101 is a digital-to-analog video converter on a single
monolithic chip. T he 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 T T L
input interface and high impedance, analog output, current
sources.
2. Compatible with a wide variety of high resolution color
graphics video systems.
3. Guaranteed monotonic with a maximum differential nonlin-
earity of ±0.5 LSB. Integral nonlinearity is guaranteed to be
a maximum of ±1 LSB.
T he 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.
T he 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.
T he ADV101 is fabricated in a +5 V CMOS process. Its mono-
lithic 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 carrier,
PLCC.
