General Description
The MAX3861 is a low-power amplifier with automatic
gain control (AGC), designed for WDM transmission
systems employing optical amplifiers and requiring a
vertical threshold adjustment after the post amp.
Operating from a single 3.3V supply, this AGC amplifier
linearly amplifies/attenuates the input signal while main-
taining a fixed output-voltage swing at data rates up to
2.7Gbps. The input and output are on-chip terminated
to match 50 interfaces.
This amplifier has a small-signal bandwidth of 3.4GHz
and an input-referred noise of 0.26mVRMS. Over an
input signal range of 6mVP-P to 1200mVP-P (46dB), the
MAX3861 delivers a constant output amplitude
adjustable from 400mVP-P to 920mVP-P. Variation in
output swing is controlled within 0.2dB over a 16dB
input range. The MAX3861 provides a received-signal-
strength indicator (RSSI) that is linear, within 2.5%, for
input signal levels up to 100mVP-P and an input signal
detect (SD) with programmable threshold.
