Abstract:
In accordance with embodiments disclosed herein, there is provided systems and methods for jitter sensing and adaptive control of parameters of clock and data recovery (CDR) circuits. A receiver component includes an adaptive CDR loop dynamic control circuit. The adaptive CDR loop dynamic control circuit is to detect first sinusoidal jitter at a first frequency and a first amplitude and update parameters of the CDR circuit to a first plurality of values based on the first frequency and the first amplitude. The adaptive CDR loop dynamic control circuit is further to detect second sinusoidal jitter at a second frequency and a second amplitude and update the parameters of the CDR circuit to a second plurality of values based on the second frequency and the second amplitude. The first sinusoidal jitter is in a first incoming data signal and the second sinusoidal jitter is in a second incoming data signal.
