MAX3272EGP

Overview

The MAX3272EGP is a single-channel, 2.5Gbps limiting amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V power supply with a typical supply current of 33mA. The device features CML output interface and is housed in a 20-pin, 4mm x 4mm QFN or Thin QFN package. Key electrical characteristics include 5ps deterministic jitter and 90ps edge speed. It includes programmable loss-of-signal indication and an optional squelch function.

Feature Summary

• Accepts wide range of input voltages to provide constant-level output voltage with controlled edge speeds
• Integrates power detectors with programmable loss-of-signal indication for signal integrity monitoring
• Offers optional squelch function that mutes data output when input voltage falls below threshold
• Provides 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 EGP corresponds to the 20-pin 4mm x 4mm QFN or Thin QFN package configuration. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any product change notifications or end-of-life declarations associated with this specific part number variant before procurement planning.

Selection Notes

Select this component for high-speed optical receiver applications requiring low jitter and low power consumption. Ensure the design supports a single +3.3V supply. Verify that the CML output interface matches the downstream logic requirements. Consider the thermal performance of the QFN package for the intended operating environment.

Part Context

The MAX3272 belongs to Maxim Integrated's family of high-speed limiting amplifiers designed for optical communication systems. It complements other transceiver components by providing signal conditioning for 2.5Gbps data rates. The EG suffix typically denotes the specific package type and temperature grade within the MAX3272 series.

Replacement Considerations

Consult official substitution guides for equivalent limiting amplifiers. Verify pin compatibility and electrical specifications against alternatives such as the MAX3272A or other high-speed optical receiver ICs from Analog Devices.
