About adn2915, the recovered output signal at 10Gb/s is worse than the signal received after the sfp. The waveform is shown as follow.The yellow one is the input optical signal, the green one is the signal recovered by the adn2915. It becomes worse! I don't know why, if the ADN2915 is not used correctly, or the PCB is not designed good enough. Can I get the schematic and PCB document about the ADN2915? Hoping your help ! Thank you very much !!!
