Notes:

1. f = 50 MHz

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

@155Mb assuming detector responsivity of 0.9
