ABSTRACT:
A system and method for frequency recovery that allows selection between either a synchronous recovery scheme or asynchronous recovery. A frequency recovery system for synchronizing a received data stream, comprising: a first timing signal generator configured to receive the data stream, extract any timing information included in the data stream, and output a first timing signal based on the extracted timing information;a clock source for providing a second timing signal; a data module for receiving the data stream and outputting the data stream at a desired rate, the data module utilizing either the first timing signal or the second timing signal to output the data at the desired rate; and a switch for selectively applying either the first timing signal or the second timing signal to the data module.
