Abstract: A receiver includes: equalizer circuitry; clock and data recovery (CDR) circuitry; sampler circuitry; adaptation circuitry; and clock adjustment circuitry. The receiver is configured to: receive data via a channel; perform equalization operations on received data, the equalization operations resulting in equalization results; perform sampling operations responsive to the equalization results, the sampling operations resulting in data samples and error samples; perform adaptation operations responsive to the data samples and the error samples, the adaptation operations resulting in a clock adjustment control signal; and adjust a sampling clock signal relative to a CDR clock signal responsive to the clock adjustment control signal.
