Separate strobe and data clock recovery keeps sampling aligned, reducing jitter and encoding overhead in high-speed parallel I/O.
Multi-step frequency tracking and dynamic accumulator ranges let clock data recovery lock under large offsets while maintaining jitter tolerance.
Dual resync and retimer modes adjust delay and clock phase to cut latency, reduce jitter, and avoid extra power-hungry CDR stages.
A PLL and reference clock keep all-slave ring nodes within frequency limits, preventing rotating unlock and data errors.
Two PLLs split clock tracking and holdover, letting slave nodes detect timing error and correct resynchronization after downstream outages.
One SerDes architecture switches between point-to-point and point-to-multipoint modes to balance lock time, jitter, and manufacturing cost.
Recovered data timing is cleaned by a PLL and fed back as the reference clock, cutting jitter and removing external oscillators.
