32Gbaud PAM4 Clock Recovery Module With A SFP28/56 Optical Port

32Gbaud PAM4 Clock Recovery Module With A SFP28/56 Optical Port

  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 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.

  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.

   32G clock recovery instrument is a kind of test equipment for high speed digital communication system, which is used to extract and recover the clock signal from the input signal. In high-speed digital communications, the stability and accuracy of the clock signal are crucial for the correct transmission of data. Because the signal may be affected by noise, distortion and other factors in the transmission process, resulting in the quality of the clock signal decline, it is necessary to use the clock recovery instrument to extract and recover high-quality clock signals.
