CR3302 120 GBaud Clock Recovery Unit
Semight CR3302 is a compact, cost-effective and efficient desktop high-speed signal clock recovery unit, which supports either Non-Return-to-Zero (NRZ) or Pulse Amplitude Modulation 4-level (PAM4) signals clock recovery at 25~120 GBaud. It is widely used in 1.6T optical transceiver and Interface test and measurement. Benefiting from its high sensitivity, low intrinsic jitter, and excellent measurement accuracy, the CR3302 is able to recover clocks from closed-eye signals
