Abstract
A data channel circuit including an analog to digital converter, a timing loop control circuit, an interpolator circuit, and a deglitch circuit. The analog to digital converter is configured to convert an analog input signal into a corresponding digital signal in accordance with a reference clock signal received from a timing loop. The timing loop control circuit is configured to receive the digital signal from the analog to digital converter, and generate a first clock signal based on the digital signal. The interpolator circuit is configured to receive the first clock signal, and generate a second clock signal based on the first clock signal, and the first clock signal delayed by a predetermined phase delay. The second clock signal has first glitches. The deglitch circuit is configured to, based on the second clock signal, generate the reference clock signal. The reference clock signal does not include the first glitches.
