Overview

  • +3.0V to +5.5V Supply Voltage
  • Low Deterministic Jitter
    • 14ps (MAX3264)
    • 11ps (MAX3265/MAX3765)
      • 150ps (max) Edge Speed (MAX3265/MAX3765)
      • 300ps (max) Edge Speed (MAX3264)
      • Programmable Signal-Detect Function
      • Choice of CML or PECL Output Interface
      • 10-Pin µMAX or 16-Pin TSSOP Package

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 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 positive-referenced emitter-coupled logic (PECL) data outputs and are available in a tiny 10-pin µMAX® package that is ideal for small-form-factor (SFF) receivers.
