... The AGC function allows 0dBm input overload. The CS6704 amplifies the current generated by a PIN diode or avalanche photodiode and converts this to a differential output voltage. The PINK output of the CS6704 is connected to V through a 1.2kΩ on-chip resistor. By using a CC bypass capacitor at this pin, a filter function significantly reduces the amount of noise at the cathode of the photodiode ...

... The single-ended output of transimpedance amplifier is converted to differential signal through output buffer able to drive either a 50Ω load or a high impedance load. The output swing will be smaller when the CS6704 is terminated with a 50Ω load. For better noise rejection, the different output should be terminated symmetrically. ...
