Dear engineers:

I have a big problem about the ADN2915.

The yellow one is the received optical signal, the green one is the output electronic signal recovered by the adn2915. Why do the signal becomes worse after the adn2915? If it is not good enough of the PCB or the function of the ADN2915 is not used corrected. Can you give me some advise or if it is possible to get the PCB and the schematic documents about ADN2915?

Hoping for help! Thank you very much !
