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
