High resolution color graphics Digital radio modulation Image processing Instrumentation Video signal reconstruction Automotive infotainment units GENERAL DESCRIPTION The ADV7125 (ADV) is a triple high speed, digital-to-analog The ADV7125 is fabricated in a 5 V CMOS process. Its converter (DAC) on a single monolithic chip. It consists of three monolithic CMOS construction ensures greater functionality high speed, 8-bit video DACs with complementary outputs, a with lower power dissipation. The ADV7125 is available in 48- standard TTL input interface, and a high impedance, analog lead LQFP and 48-lead LFCSP packages. output current source. PRODUCT HIGHLIGHTS The ADV7125 has three separate 8-bit-wide input ports. A 1. 330 MSPS (3.3 V only) throughput. single +5 V/+3.3 V power supply and clock are all that are 2. Guaranteed monotonic to eight bits. required to make the device functional. The ADV7125 has 3. Compatible with a wide variety of high resolution color additional video control signals, composite SYNC and BLANK, graphics systems, including RS-343A and RS-170. as well as a power save mode. Rev.
