Abstract:
Apparatus and method for clock and data recovery are disclosed. A reset circuit counts clock cycles between edges of an input signal and resets a signal processing circuit that performs acquisition and tracking of a data stream when the clock cycle count is outside of a range. The signal processing circuit is further configured to perform acquisition and tracking according to a corrected data rate, which can be generated by data rate adjustment through a phase error correcting control loop and/or dithering between two data rates.
