MAX3272AETP+T

Overview

The MAX3272AETP+T is a 2.5Gbps limiting amplifier manufactured by Analog Devices Inc./Maxim Integrated. It accepts a wide range of input voltages and provides a constant-level output voltage with controlled edge speeds. The device operates on a single +3.3V power supply with a typical supply current of 33mA. Key electrical characteristics include 5ps deterministic jitter and 90ps edge speed. It features a CML output interface and is available in a 20-pin, 4mm x 4mm QFN or Thin QFN package.

Feature Summary

• Provides constant-level output voltage with controlled edge speeds for high-speed signal integrity
• Includes power detectors with programmable loss-of-signal indication
• Features an optional squelch function that mutes the data output when input voltage falls below a threshold
• Offers selectable output polarity for flexible system integration

Applications

• Gigabit Ethernet Optical Receivers
• Fibre Channel Optical Receivers
• System Interconnects
• 2.5Gbps Optical Receivers
• SONET/SDH Receivers

Procurement Notes

Verify the specific suffix ETP against the official datasheet to confirm the package type and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements as indicated by the plus sign in the part number. Cross-reference the manufacturer's latest documentation for any updates regarding lead-free status or environmental declarations before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring low-power operation at 2.5Gbps data rates. The integrated squelch and loss-of-signal detection simplify receiver design by reducing external logic requirements. Consider the CML output interface compatibility with downstream circuitry. The small form factor QFN package is suitable for space-constrained designs where thermal management and signal integrity are critical.

Part Context

This part belongs to the MAX3272 family of limiting amplifiers designed for optical communication receivers. It complements other Maxim Integrated high-speed interface solutions by providing robust signal conditioning for serial data streams. The family supports various industrial and telecommunications standards requiring reliable performance under varying input signal conditions.
