Abstract
A flexible bit rate clock recovery unit is provided for recovering a clock signal from an input data signal, where the input data signal is transmissible at different bit rates. The flexible bit rate clock recovery unit includes a plurality of fixed rate clock recovery units, where each fixed rate clock recovery units is operative at a different bit rate to extract an intermediary clock signal from the input data signal; a comparator for generating an encoded data signal based on an amplitude characteristic of each of the intermediary clock signals, where the encoded data signal is indicative of the clock signal associated with the input data signal; and a selector for selecting one of the intermediary clock signals based on the encoded data signal, thereby recovering the clock signal from the input data signal.
