Let's talk off line. Please contact me at dongfeng.Zhao@analog.com.
Please elaborate your design in a schematic. We need following information:
1. the photonic detector schematic;
2. confirmation of if the photonic detector output works as a voltage or a current output source?
3. the photonic detector P-I (optical average power on photonic detector vs. output current) at your specified
reversed bias voltage.
Per your interested signal data rate range requirement, you might consider ADN2880 and ADN2882 as well.
However, these three TIAs share the similar circuitry architecture. In general, they are not suitable to work with
your common anode type of photo-diode directly at reverse bias voltage = 2V, since their IN voltage is clamped to
