Question

Write short note on ClockRecovery

Answer 1

In serial communication of digital data, clock recovery is the process of extracting timing information from a serial data stream to allow the receiving circuit to decode the transmitted symbols. Clock recovery from the data stream is expedited by modifying the transmitted data. Wherever a serial communication channel does not transmit the clock signal along with the data stream, the clock must be regenerated at the receiver, using the timing information from the data stream. Clock recovery is a common component of systems communicating over wires, optical fibers, or by radio.
