2.5Gbps, +3V to +5.5V, Wide Dynamic Range
Transimpedance Preamplifier
General Description
The MAX3864 is a transimpedance preamplifier for
applications in SDH/SONET systems operating up to
2.5Gbps. It features 490nA (typ) input-referred noise,
2.0GHz bandwidth, and 2mA input overload.
The MAX3864 operates from a single +3.0V to +5.5V
supply. It includes an integrated low-frequency com-
pensation capacitor, as well as a filter connection that
provides positive bias through a 750Ω resistor to V_CC.
These features save external components, simplifying
design and assembly into a TO-46 header with a photo-
diode.
The MAX3864 has a typical optical dynamic range of
-24dBm to 0dBm using a PIN photodetector.
