CR4201

10G Clock Recovery Unit

Semight Instruments CR4201 is a clock recovery unit used in conjunction with the optical sampling oscilloscopes. Sampling oscilloscopes need a clock to trigger for eye-diagram testing. When a clock or trigger signal is not provided by the device under testing，such as ONT(Optical Network Terminal) or other line-card, CR4201 is the best choice to derive a clock from the data being measured.

CR4201 supports flexible & adaptive data rate range of 1.25 ~ 10.3125 Gbps clock recovery.
