MAX3272

19-2269; Rev 3; 11/04 KIT ATION EVALU E L B A AVAIL +3.3V, 2.5Gbps Low-Power Limiting Amplifiers General Description Features ♦ Single +3.3V Power Supply ♦ 33mA Supply Current ♦ 5ps Deterministic Jitter ♦ 90ps Edge Speed ♦ Output Squelch Function ♦ Programmable Loss-of-Signal Function ♦ CML Output Interface ♦ 20-Pin 4mm ✕ 4mm QFN or Thin QFN Package ♦ 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 signal 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 connectors, and are available in a 4mm ✕ 4mm QFN package or in die form (MAX3272 only). Along with the MAX3271, the MAX3272/MAX3272A are ideal for lowpower, compact optical receivers.
