Abstract
An apparatus for recovering a clock from a data signal includes an out-of-lock detector configured to detect when a receiver data clock has a frequency offset with respect to a transmitter data clock associated with the data signal, an out-of-lock counter configured to count out-of-lock conditions for the receiver data clock, and a loop filter configured to correct the frequency offset in the receiver data clock based at least in part on the count of out-of-lock conditions.
