MAX3265EUE+

Overview

The MAX3265EUE+ is a +3.0V to +5.5V, 2.5Gbps 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 a typical deterministic jitter of 11ps, random jitter of 8ps RMS, and a maximum edge speed of 150ps.

Feature Summary

• Provides low deterministic jitter performance suitable for high-speed serial links
• Features programmable loss-of-signal indication via RMS power detection
• Includes an optional squelch function that mutes the output when input signals fall below a threshold

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the '+' suffix denotes lead-free compliance. Ensure the 16-pin TSSOP-EP package matches the target PCB footprint requirements. Check for RoHS directive alignment before finalizing procurement.

Selection Notes

Select this component for applications requiring CML outputs and operation up to 2.5Gbps. It is suitable for GBIC receivers due to its tolerance for inductive connectors. Consider the MAX3264 variants if a lower data rate of 1.25Gbps is sufficient, or the MAX3268 series if PECL outputs are preferred over CML.

Part Context

This part belongs to the Maxim Integrated MAX3264/MAX3265/MAX3268/MAX3269 family of limiting amplifiers. These devices are engineered for optical receiver systems operating at 1.25Gbps or 2.5Gbps. The MAX3265 variant specifically offers CML outputs and is packaged in a 16-pin TSSOP format.

Replacement Considerations

The MAX3264EUE+ serves as a functional substitute for 1.25Gbps applications within the same package. For PECL output requirements, the MAX3268EUE+ is an alternative. Verify pin compatibility and thermal characteristics when substituting.
