AD809BR-REEL7 Description

Short technical summary and product information.

The AD809BR-REEL7 is a clock/frequency synthesizer designed to generate a 155.52 MHz output clock from either a 19.44 MHz or 9.72 MHz reference input. It incorporates a phase-locked loop (PLL) and supports differential inputs and outputs with a 2:1 input-to-output ratio.

 

Key specifications include operation from a single supply of 4.5V to 5.5V (positive) or -5.2V (negative), typical power consumption of 90 mW, and output jitter of 2.0 degrees RMS typical. The device operates over a -40°C to 85°C temperature range and features a jitter transfer bandwidth of 200 kHz typical.

 

The AD809BR-REEL7 is suitable for SONET/SDH and Fiber in the Loop systems requiring a low-jitter 155.52 MHz bit clock. The on-chip VCO eliminates external components for frequency synthesis, though loop dynamics can be adjusted with an external damping capacitor. The design ensures output frequency drifts low (approximately 20%) if the input signal is lost.

 

The device is supplied in a 16-pin narrow SOIC (SOIC-16) with Gull Wing leads for surface mounting. Tape and reel packaging facilitates automated assembly processes.
