ABSTRACT:
A digital phase-locked loop for receiving an encoded stream of data and generating a receive clock signal therefrom is provided with a counter, such as a down counter, having an adjustable start count value. An edge detector detects the rising and falling edges within a stream of data. The detection of an edge causes the counter to start counting from the start count value towards a terminal value. A receive clock generator is provided that generates a receive clock signal, the receive clock generator being responsive to the counter reaching at least a first predetermined value to change a level of the receive clock signal. The use of a down counter that is loaded with a start count value upon the detection of an edge provides fast re-synchronization when an edge has been missed, while providing accurate recovery of the clock from the encoded stream of data.
