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 ADV is a registered trademark of Analog Devices, Inc. |
