MAX3264CUE+T

Overview

The MAX3264CUE+T is a +3.0V to +5.5V, 1.25Gbps limiting amplifier designed for Gigabit Ethernet and Fibre Channel optical receiver systems. It accepts wide input voltage ranges and provides constant-level outputs with controlled edge speeds. The device features current-mode logic (CML) data outputs tolerant of inductive connectors and is housed in a 16-pin TSSOP package with an exposed paddle. Key specifications include low deterministic jitter of 14ps peak-to-peak and a maximum edge speed of 300ps.

Feature Summary

• Provides CML data outputs suitable for GBIC receivers
• Includes programmable loss-of-signal indication via RMS power detection
• Features optional squelch function to mute data output when signal falls below threshold
• Offers excellent jitter performance with integrated offset correction

Applications

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

Procurement Notes

Verify the component matches the exact part number MAX3264CUE+T. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package type is 16-pin TSSOP with an exposed paddle. Check that the temperature range corresponds to 0°C to +70°C. Validate RoHS compliance status as indicated by the '+' suffix.

Selection Notes

Select this component for applications requiring 1.25Gbps data rates with CML outputs. It is ideal for small-form-factor receivers where low jitter is critical. Consider the exposed paddle for thermal management. Verify compatibility with the specific optical receiver architecture and termination requirements.

Part Context

This part belongs to the MAX3264/MAX3265/MAX3268/MAX3269/MAX3765/MAX3768 family of limiting amplifiers. The MAX3264 variant specifically supports 1.25Gbps data rates and utilizes CML outputs. Other family members may support 2.5Gbps or use PECL outputs.
