GENERAL DESCRIPTION
The ADV7123 (ADV®) is a triple high speed, digital-to-analog
converter on a single monolithic chip. It consists of three high
speed, 10-bit, video DACs with complementary outputs, a
standard TTL input interface, and a high impedance, analog
output current source.
The ADV7123 has three separate 10-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 ADV7123 has additional video
control signals, composite SYNC and BLANK .
The ADV7123 also has a power save mode.

The ADV7123 is fabricated in a 5 V CMOS process. Its
monolithic CMOS construction ensures greater functionality
with lower power dissipation. The ADV7123 is available in a
48-lead LQFP package.
PRODUCT HIGHLIGHTS
1.
330 MSPS throughput.
2.
Guaranteed monotonic to 10 bits.
3.
Compatible with a wide variety of high resolution color
graphics systems, including RS-343A and RS-170.
