100Gbps Multi - Frequency Division Clock Recovery Instrument

100Gbps Multi-Frequency Division Clock Recovery Instrument

   U9764A CDR (Clock Recovery Module ) is mainly used to provide clock recovery signal in the test environment without triggering clock, so as to use the sampling oscilloscope to test the optical eye diagram of the device. The typical application is the testing of optical network equipment or the BOB prodUt in PON application. Because the photometric device itself has no frequency division clock output, it is necessary to recover the clock signal to trigger the sampling oscilloscope when testing the optical eye diagram.

   U9764A CDR has a SFP28 optical port, which is suitable for SFP encapsulated conventional SFP28, SR,LR,BIDI and other optical modules. It only needs the receiving end of the optical module to convert the optical signal to the electrical signal, and then extract and output the clock of the electrical signal. Clock signal is mainly used for the trigger signal of oscilloscope.

The full name of CDR is Clock and Data Recovery. As the name suggests, the main functions of CDR are:

1) to provide the clock signal for each circuit at the receiver end.

2) to judge the received signal, to facilitate the recovery and subsequent processing of the data signal.
