3.2Gbps SFP Transimpedance

Amplifiers with RSSI

ELECTRICAL CHARACTERISTICS (continued)

= +2.97V to +3.63V and T = -40°C to +85°C. Typical values are at V

= +3.3V, source capacitance (C ) = 0.85pF, and T =

CC IN A

+25°C, unless otherwise noted.) (Notes 1, 2)

at 3.3V, +25°C (Note 3)

Note 1: Dice are designed to operate with junction temperatures of -40°C to +110°C but are tested and guaranteed only at T = 25°C.

Note 2: Source capacitance represents the total capacitance at the IN pad during characterization of the noise and bandwidth para-

meters.

Note 3: Guaranteed by design and characterization.

Note 4: Input-referred noise is:

Note 5: Deterministic jitter is the sum of pulse-width distortion (PWD) and pattern-dependent jitter (PDJ).

Note 6: Power-supply noise rejection PSNR = -20log(∆V / ∆V ), where ∆V is the differential output voltage and ∆V is the
