It consists of a 10-bit, video DAC with an on-board voltage 1. 240 MSPS throughput. reference, complementary outputs, a standard TTL input 2. Guaranteed monotonic to 10 bits. interface, and high impedance analog output current sources. 3. Compatible with a wide variety of high resolution color The ADV7127 has a 10-bit wide input port. A single 5 V or graphics systems including RS-343A and RS-170. 3.3 V power supply and clock are all that are required to make the device functional. The ADV7127 is fabricated in a complementary metal-oxide semiconductor (CMOS) process. Its monolithic CMOS construction ensures greater functionality with low power dissipation. The ADV7127 is available in a 24-lead TSSOP package which includes a power-down mode and an on-board voltage reference circuit. Rev.
