CR4201
10G Clock Recovery Unit
Semight CR4201 is a clock recovery unit used in conjunction with the optical sampling oscilloscopes. Sampling oscilloscopes need a clock to trigger it for eye-diagram testing. When a clock or trigger signal is not provided by the device under test，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.
- Rate Adaptation – 1.25~10.3125 Gbps, Rate Adaptation
- Single mode multi-mode integrated – Supports both single-mode and multi-mode optical signal clock recovery
- High sensitivity – Single-mode multi-mode minimum optical power -20dBm
- Adjustable loop bandwidth – 500k~3.5M Adjustable loop bandwidth
