Abstract

A system for recovering a payload data stream from a framing data stream utilizes a buffer, a first counter, a second counter, and a clock synchronization element. The buffer is configured to receive the framing data stream and to store payload bits of the framing data stream. The buffer is further configured to transmit the payload bits based on a clock signal. The first counter is configured to produce a first value and to update the first value for each of the payload bits stored in the buffer. The second counter is configured to produce a second value and to update the second value based on the clock signal. The clock synchronization element is coupled to the first and second counters. The clock synchronization element is configured to compare the first and second values and to control a frequency of the clock signal based on comparisons of the first and second values.
