MAX3265CUB+T

Overview

The MAX3265CUB+T is a +3.0V to +5.5V, 2.5Gbps limiting amplifier designed for Gigabit Ethernet and Fibre Channel optical receiver systems. It accepts a wide range of input voltages and provides constant-level output voltages with controlled edge speeds. The device features current-mode logic (CML) data outputs tolerant of inductive connectors and is housed in a 10-pin µMAX package with an exposed paddle.

Feature Summary

• Provides low deterministic jitter performance
• Includes programmable signal-detect function with loss-of-signal indication
• Features CML data outputs suitable for GBIC receivers

Applications

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

Procurement Notes

Verify the component matches the specific 10-pin µMAX package configuration and lead-free designation. Confirm that the operating temperature range aligns with system requirements, as variations exist within the family. Ensure the ordering suffix corresponds to the intended thermal and electrical specifications before procurement.

Selection Notes

Select this part when a compact form factor is required for high-speed optical applications. The 10-pin µMAX package is ideal for small-form-factor receivers compared to larger TSSOP options. Verify compatibility with the system's power supply voltage range and ensure the CML output interface matches the downstream circuitry requirements.

Part Context

This component belongs to the MAX3264/MAX3265/MAX3268/MAX3269/MAX3765/MAX3768 family of limiting amplifiers. While other variants offer PECL outputs or different pin counts, the MAX3265CUB+T specifically utilizes CML outputs and a 10-pin footprint optimized for space-constrained designs.

Replacement Considerations

The MAX3265CUB is a non-lead-free equivalent. The MAX3765CUB+T offers identical functionality but includes an internally enabled squelch function.
