(1) The small signal bandwidth is specified over process corners, temperature, and supply voltage variation. The assumed photodiode capacitance is 0.1pF and the bond-wire inductance is 0.3nH. The small signal bandwidth strongly depends on environmental parasitics. Careful attention to layout parasitics and external components is necessary to achieve optimal performance.
(2) Input referred RMS noise is (RMS output noise)/ (gain at 100 MHz).
(3) Die only, no wire bonds
(4) PSRR is the differential output amplitude divided by the voltage ripple on the supply. No input current at IN.
