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. Both the input and output are on-chip termi-
nated to match 50
interfaces.
This amplifier has a small-signal bandwidth of 3.4GHz
and an input-referred noise of 0.26mV
RMS
. Over an
input signal range of 6mV
P-P
to 1200mV
P-P
(46dB), the
MAX3861 delivers a constant output amplitude that is
adjustable from 400mV
P-P
to 920mV
P-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 100mV
P-P
and an input signal
detect (SD) with programmable threshold.
