GENERAL DESCRIPTION

The ADV7123 (ADV

converter on a single monolithic chip. It consists of three

high speed, 10-bit, video D/A converters 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 mono-

lithic 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
