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 “Input Referred Noise Current.”
(6) CAGC = 56 pF
(7) Parameter is guaranteed (not tested) by
design and characterization data @ 622 Mb/s, assuming detector responsively
of 0.95.
