U9720B 32 Gbaud PAM4 CDR

   U9720B 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.

   U9720B CDR has a FC optical interface adapter, which is suitable for optical signal access of conventional SFP28/56, SR, LR and BIDI modules. It supports NRZ and PAM4 signals. FC optical interface receives optical signals and converts them into electrical signals. CDR then abstracts and outputs the clock of electrical signals, and the clock signals are mainly used for the trigger signals of oscilloscopes.

     U9720B CDR（时钟恢复仪）主要用于在没有触发时钟的测试环境，提供时钟恢复信号，从而利用采样示波器测试器件的光眼图。典型应用是光网络设备的测试，或者针对PON应用中的BOB产品，由于被测光设备本身没有分频时钟输出，在测试光眼图时需要恢复时钟信号用于触发采样示波器。

     U9720B CDR带有一个FC光接口适配器，适用于常规SFP28/56、SR、LR和BIDI等模块的光信号接入，支持NRZ及PAM4信号，FC光接口接收光信号转换为电信号，CDR再将电信号的时钟提取出来并输出，时钟信号主要用于示波器的触发信号。
