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 750

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.
