Hello Ivan,
The ONET8501T is a high gain TIA and there is a high chance for an oscillation to occur if a two terminal PD is used, especially with TO-can packaging. It is recommended to only use a 3 terminal GSG type PD with the ONET8501T as shown in…
Hello Eric,
Since the bandwidth of a TIA is inversely proportional to the total input capacitance (TIA input capacitance + photodiode capacitance), the large PD capacitance can reduce the BW by up to 5 times the typical value. However, it will also impact…
Ivan,
Pads 7 and 9 are internally connected on the ONET8551T. Therefore, either pad 7 or pad 9 can be used to supply the reverse bias voltage to the cathode of the PD.
Kpk,
In general, all bond wire lengths should be made as short as possible. The bond wire from the APD anode to the TIA should be in the 300um range. Also, it is highly recommended to use a header with 50ohm pins. The attached file has some recommendations…
