PRODUCT DESCRIPTION
The AD809 provides a 155.52 MHz ECL/PECL output clock from either a 19.44 MHz or a 9.72 MHz TTL/CMOS/ECL/PECL reference frequency. The AD809 functionality supports a distributed timing architecture, allowing a backplane or PCB 19.44 MHz or 9.72 MHz timing reference signal to be distributed to multiple 155.52 Mbps ports. The AD809 can be applied to create the transmit bit clock for one or more ports.
