General 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 FUNCTIONAL BLOCK DIAGRAM CF1 CF2 7 8 (19.44MHz CLKIN 13 OR 9.72MHz) CLKINN 12 AUTO SELECT PFD LOOP FILTER BW ADJUST VCO TTL/CMOSIN 10 AUTO SELECT DIVIDE BY 8/16 AD809 PECLIN 2 (155MHz) PECLINN 1 MUX 15 MUX 5 4 CLKOUT CLKOUTN (155MHz PECL OUTPUT) REV.
