CR3302
120GBaud Clock Recovery Unit
Nexustest 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 25~120GBaud. 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.
