HMC799 feedback capacitance

I'm working on a photodiode circuit design using HMC799. When I calculate and evaluate the noise gain, I couldn't find any information related to the parasitic capacitance of the feedback resistor. As the feedback resistor is integrated inside the chip HMC799, the parasitic capacitance might be extremely small. If so, the circuit's stability becomes an issue. Is there any extra information I can use to calculate the noise gain model?
