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 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.
