Notes:
1. f = 50MHz
2. Measured with Iin below AGC Threshold. During AGC, input impedance will
decrease proportionally to Iin.
3. Defined as the Iin where Transresistance has decreased by 50%.
4. See note on Indirect Measurement of Optical Overload.
5. See note on Measurement of Input Referred Noise Current.
6. CAGC = 220 pF
7. Parameter is guaranteed (not tested) by design and characterization data
@ 1.2 Gb/s, assuming dectector responsivity of 0.9.
