It consists of a 10-bit, video D/A converter with on-board voltage reference, comple- mentary outputs, a standard TTL input interface and high impedance analog output current sources. The ADV7127 has a 10-bit wide input port. A single +5 V/ +3.3 V power supply and clock are all that are required to make the part functional. The ADV7127 is fabricated in a CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7127 is available in a small outline 28-lead SOIC or 24-lead TSSOP package. The ADV7127 TSSOP package also has a power-down mode. Both ADV7127 packages have a power standby mode. The ADV7127 TSSOP package has an on-board voltage refer- ence circuit. The ADV7127 SOIC package requires an external reference. PRODUCT HIGHLIGHTS 1. 240 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-170A. ADV is a registered trademark of Analog Devices, Inc. |
