Jitter sensing and adaptive control of parameters of clock and data recovery circuits
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.
