Analog Devices AD809 Frequency Synthesizer Datasheet
The AD809 is a frequency synthesizer designed to generate a 155.52 MHz clock signal from either a 19.44 MHz or 9.72 MHz input reference. It features an on-chip voltage-controlled oscillator (VCO) that locks to the input frequency, eliminating the need for external components for basic operation. The device is optimized for SONET/SDH and Fiber in the Loop systems.
