Datasheet
The MAX3866 combined transimpedance preamplifier
and limiting postamplifier is intended for application in
SDH/SONET systems operating at 2.488Gbps. It oper-
ates from a single +3.3V or +5V supply and provides a
differential output signal. The differential outputs are
each 50Ω reverse terminated (100Ω differential termi-
nation) for low-noise and high-speed signal perfor-
mance.
The small-signal bandwidth and noise performance is
specified for a source capacitance of 0.5pF. When the
MAX3866 is used with the PIN photodetector, sensitivi-
ties better than -22dBm can be achieved. The
MAX3866 is equipped with a programmable TTL loss-
of-power (LOP) output.
