Datasheet
The AD809 is a 155.52 MHz frequency synthesizer that can be used to create a 155.52 Mbps port's transmit bit clock. The device has a low jitter VCO, low power and wide operating temperature range, making it suitable for generating a 155.52 MHz bit clock for SONET/SDH/Fiber in the Loop systems.
Datasheet
The AD809 is a 155.52 MHz frequency synthesizer that can be used to generate 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; however, the user can adjust the input frequency to achieve optimum performance.
