Abstract
Techniques to operate circuitry in an integrated circuit are provided. The circuitry may include rate detection circuitry, receiver circuitry, and configuration circuitry. The receiver circuitry may receive a data stream with an arbitrary data rate. The rate detection circuitry may receive a reference clock signal that is associated with the received data stream. The rate detection circuitry determines the frequency of the reference clock signal such that an appropriate clock signal may be generated for the receiver circuitry. The receiver clock signal may be generated by clock generation circuitry that is coupled to the rate detection circuitry. The configuration circuitry may accordingly configure the receiver circuitry based at least on the determined frequency of the reference clock signal so that the receiver circuitry may operate at the arbitrary data rate.
