GENERAL DESCRIPTION

The ADV101 is a digital-to-analog video converter on a single
monolithic chip. The part is specifically designed for high reso­lution 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 sig­nals, 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 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 carrier,
PLCC.

operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADV101 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
