U9720A 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 product 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.
U9720A CDR has a SFP28/56 optical port, which is suitable for
SFP28/56 encapsulated conventional SFP28/56, SR,LR,BIDI and other
optical modules. It is Support for NRZ and PAM4 signals. And 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.
