MAX3268 General Description
The 1.25Gbps MAX3264/MAX3268/MAX3768 and the 2.5Gbps MAX3265/MAX3269/MAX3765 limiting amplifiers 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 signal when the input voltage falls below a programmable hreshold, 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 positive-referenced emitter-coupled logic (PECL) data out puts and are available in a tiny 10-pin PAMAX packag that is ideal for small-form-factor (SFF) receivers.
