MAX3265CUE+T

Overview

The MAX3265CUE+T is a 2.5Gbps limiting amplifier designed for Gigabit Ethernet and Fibre Channel optical receiver systems. It operates from a +3.0V to +5.5V supply voltage and features current-mode logic (CML) data outputs tolerant of inductive connectors. The device provides constant-level output voltages with controlled edge speeds, low deterministic jitter, and an RMS power detector with programmable loss-of-signal indication.

Feature Summary

• Features CML data outputs suitable for GBIC receivers
• Includes RMS power detection with programmable loss-of-signal indication
• Offers optional squelch function to mute data output signals
• Provides excellent jitter performance

Applications

• Gigabit Ethernet Optical Receivers
• Fibre Channel Optical Receivers
• System Interconnect
• ATM Optical Receivers

Procurement Notes

Verify the component matches the exact part number MAX3265CUE+T. Confirm the package type is 16-pin TSSOP-EP and the operating temperature range is 0°C to +70°C. Ensure the datasheet revision aligns with the manufacturer's documentation before integration into designs.

Selection Notes

Select this component when designing optical receivers requiring 2.5Gbps data rates. It is appropriate for applications needing CML outputs and integrated signal detection. Consider the exposed paddle requirement for thermal management and proper grounding during PCB layout.

Part Context

This device belongs to the MAX3264/MAX3265/MAX3268/MAX3269/MAX3765/MAX3768 family of limiting amplifiers. While other variants offer different data rates or PECL outputs, the MAX3265CUE+T specifically provides 2.5Gbps performance with CML outputs in a 16-pin TSSOP package.

Replacement Considerations

The MAX3265EUE+T serves as a direct replacement offering extended temperature operation (-40°C to +85°C). Other family members like MAX3264 provide 1.25Gbps speeds, while MAX3268 variants feature PECL outputs.
