PRODUCT HIGHLIGHTS
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……
