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 refer-

ence 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

REV. A

155.52 Mbps ports. The AD809 can be applied to create the trans-

mit bit clock for one or more ports.

An input signal multiplexer supports loop-timed applications

where a 155.52 MHz transmit bit clock is recovered from the

155.52 Mbps received data.

The low jitter VCO, low power and wide operating temperature

range make the device suitable for generating a 155.52 MHz bit

clock for SONET/SDH/Fiber in the Loop systems.

The device has a low cost, on-chip VCO that locks to either

8 or 16 the frequency at the 19.44 MHz or 9.72 MHz input.

No external components are needed for frequency synthesis; how-

ever, the user can adjust loop dynamics through selection of a

damping factor capacitor whose value determines loop damping.

The AD809 design guarantees that the clock output frequency

will drift low (by roughly 20%) in the absence of a signal at the

input.

The AD809 consumes 90 mW and operates from a single power

supply at either +5 V or –5.2 V.
