Abstract
Technologies for jitter extraction are described. A receiver device includes an analog-to-digital converter (ADC) and a signal processing circuit. The signal processing circuit includes an equalizer block to output current data based on samples from the ADC. A clock-recovery (CR) block includes a timing error detector (TED) or a phase detector to measure a sampling offset. The CR block can use the sampling offset to control sampling of subsequent data by the ADC. A jitter extraction block can use the sampling offset to re-sample the current data to obtain re-sampled data based on the sampling offset to remove jitter from the current data.
