Description

The ADV7123 (ADV®) is a triple high speed, digital-to-analogconverter on a single monolithic chip. It consists of three highspeed, 10-bit, video DACs with complementary outputs, astandard TTL input interface, and a high impedance, analogoutput current source.The ADV7123 has three separate 10-bit-wide input ports. Asingle 5 V/3.3 V power supply and clock are all that are requiredto make the part functional. The ADV7123 has additional videocontrol signals, composite SYNC and BLANK.The ADV7123 also has a power save mode.The ADV7123 is fabricated in a 5 V CMOS process. Itsmonolithic CMOS construction ensures greater functionalitywith lower power dissipation. The ADV7123 is available in a48-lead LQFP package.PRODUCT HIGHLIGHTS 330 MSPS throughput. Guaranteed monotonic to 10 bits. Compatible with a wide variety of high resolution color graphics systems, including RS-343A and RS-170. APPLICATIONS Digital video systems (1600 × 1200 at 100 Hz) High resolution color graphics Digital radio modulation Image processing Instrumentation Video signal reconstruction
