General Description

The MAX3866 combined transimpedance preamplifier and limiting postamplifier is intended for application in SDH/SONET systems operating at 2.488Gbps. It operates from a single +3.3V or +5V supply and provides a differential output signal. The differential outputs are each 50Ω reverse terminated (100Ω differential termination) for low-noise and high-speed signal performance.

Features

♦ Input Sensitivities Better than -22dBm (7.8µAp-p)

♦ Overdrive Capability Better than +1.4dBm (2.5mAp-p)

♦ Single +3.3V or +5V Supply

♦ 165mW Power Dissipation (at 3.3V)

♦ 1.8GHz Analog Input Bandwidth

♦ Programmable Loss-of-Power Indicator

♦ 100Ω Differential Output
