MAX3268CUB-T

Overview

The MAX3268CUB-T is a limiting amplifier from the Maxim Integrated family, designed for Gigabit Ethernet and Fibre Channel optical receiver systems. It operates on a single +3.0V to +5.5V supply and supports data rates of 1.25Gbps or 2.5Gbps. The device accepts a wide range of input voltages and provides constant-level output voltages with controlled edge speeds. It features RMS power detectors with programmable loss-of-signal indication and an optional squelch function. The component is housed in a uMAX-10 package.

Feature Summary

• Provides constant-level output voltages with controlled edge speeds for high-speed digital signals
• Integrates RMS power detectors with programmable loss-of-signal indication
• Includes an optional squelch function that mutes data output when input voltage falls below a threshold

Applications

• Gigabit Ethernet optical receiver systems
• Fibre Channel optical receiver systems

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as 'T' typically denotes tape-and-reel packaging while '+T' indicates RoHS compliance. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure the ordering part number matches the specific package variant required for your design to avoid integration errors.

Selection Notes

Select this component for applications requiring precise signal conditioning in optical receivers. It is suitable where controlled edge speeds and loss-of-signal detection are critical. Verify that the operating temperature range and supply voltage requirements align with the system specifications before finalizing the design choice.

Part Context

This component belongs to the MAX326x series of limiting amplifiers manufactured by Analog Devices (Maxim Integrated). These devices are engineered specifically for high-speed serial communication interfaces. The series offers robust performance for optical interconnects, ensuring signal integrity across varying input conditions.

Replacement Considerations

Consult official substitution guides for compatible parts within the MAX3264/MAX3265/MAX3765/MAX3768 families. Verify pinout compatibility and electrical parameter alignment before replacing.
