The 1.25Gbps MAX3264/MAX3268/MAX3768 and the
2.5Gbps MAX3265/MAX3269/MAX3765 limiting ampli-
fiers are designed for Gigabit Ethernet and Fibre
Channel optical receiver systems. The amplifiers accept
a wide range of input voltages and provide constant-
level output voltages with controlled edge speeds.
Additional features include RMS 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 excellent jitter performance.
The MAX3264/MAX3265/MAX3765 feature current-mode
logic (CML) data outputs that are tolerant of inductive
connectors and a 16-pin TSSOP package, making these
circuits ideal for GBIC receivers. The MAX3268/
MAX3269/MAX3768 feature standards-compliant posi-
tive-referenced emitter-coupled logic (PECL) data out-
puts and are available in a tiny 10-pin µMAX package
that is ideal for small-form-factor (SFF) receivers.
