GENERAL DESCRIPTION

The ADV®7125 is a triple high speed, digital-to-analog converter

on a single monolithic chip. It consists of three high speed, 8-bit

video DACs with complementary outputs, a standard TTL input

interface, and a high impedance, analog output current source.

The ADV7125 has three separate 8-bit-wide input ports. A single

5 V/3.3 V power supply and clock are all that are required to make

the part functional. The ADV7125 has additional video control

signals, composite SYNC and BLANK, as well as a power-

save mode.

The ADV7125 is fabricated in a 5 V CMOS process. Its mono-

lithic CMOS construction ensures greater functionality with

lower power dissipation. The ADV7125 is available in a 48-lead

LQFP package.

PRODUCT HIGHLIGHTS

1. 330 MSPS (3.3 V only) throughput

2. Guaranteed monotonic to eight bits

3. Compatible with a wide variety of high resolution color

graphics systems, including RS-343A and RS-170
