Selectable Output Polarity
MAX3272/MAX3272A
The MAX3272/MAX3272A 2.5Gbps limiting amplifiers
accept a wide range of input voltages and provide a
constant-level output voltage with controlled edge
speeds. Additional features include power detectors
with programmable loss-of-signal (LOS) indication, an
optional squelch function that mutes the data output sig-
nal when the input voltage falls below a programmable
threshold, and an output polarity selector. These parts
exhibit excellent jitter performance and have low power
dissipation.
The MAX3272/MAX3272A feature current-mode logic
(CML) data outputs that are tolerant of inductive con-
nectors, and are available in a 4mm

4mm QFN pack-
age or in die form (MAX3272 only). Along with the
MAX3271, the MAX3272/MAX3272A are ideal for low-
power, compact optical receivers.
