AD808, Fiber Optic Receiver with Quantizer and Clock Recovery and Data Retiming
The AD808 provides the receiver functions of data quantization, signal level detect, clock recovery and data retiming for 622 Mbps NRZ data.
The device, together with a PIN diode/preamplifier combination, can be used for a highly integrated, low cost, low power SONET OC-12 or SDH STM-4 fiber optic
a Fiber Optic Receiver with Quantizer and Clock Recovery and Data Retiming AD808 frequency acquisition without false lock.
This eliminates a reliance on external components such as a crystal or a SAW filter, to aid frequency acquisition.
The AD808 acquires frequency and phase lock on input data using two control loops that work without requiring external control.
The frequency acquisition control loop initially acquires the frequency of the input data, acquiring frequency lock on random or scra
