Clock & Data Recovery

Clock & Data Recovery

Semtech’s single-lane CDRs offer the highest performance in power consumption, receiver sensitivity, output jitter and jitter tolerance. Our dual-lane signal conditioners with integrated VCSEL, DML or EML driver, offer one of the lowest power and smallest footprint solutions for XFP and retimed SFP+ modules, and our multi-lane signal conditioners enhance the reach and quality of high-speed serial links, compensating for transmission loss and re-setting crosstalk and jitter budget.
