Abstract
Systems and methods for smoothing jitter generated by byte stuffing. A frequency synthesizer comprises a smoothing logic coupled with a PLL. The smoothing logic is configured to modify a phase error signal generated by a phase frequency detector into a distributed phase error signal that spread over multiple clock cycles. The distributed phase error signal is used to drive a DCO. The smoothing logic may comprise a ramping logic operable to generate a series of ramping values to substitute a phase difference in the phase error signal. The phase difference may correspond to a stuffing byte.
