MAX3747EUB

Overview

The MAX3747EUB is a multirate limiting amplifier designed as a data quantizer for optical receivers. It supports OC-3 through OC-48 Synchronous Optical Network (SONET), Fibre-Channel, and Gigabit Ethernet applications. The device operates within an industrial temperature range of -40°C to +85°C and utilizes a 10-pin uMAX or uSOP surface-mount package with a 3.00mm width.

Feature Summary

• Supports high-speed data rates from 155Mbps to 3.2Gbps
• Optimized for SONET, Fibre-Channel, and Gigabit Ethernet optical receivers
• Provides pin-for-pin compatibility with the MAX3747A variant

Applications

• OC-3 through OC-48 SONET systems
• Fibre-Channel optical receiver interfaces
• Gigabit Ethernet optical transceivers
• Small Form-factor Pluggable (SFP) limiters

Procurement Notes

Verify current availability status directly with Analog Devices or authorized distributors, as component lifecycle stages may affect supply. Confirm exact ordering suffixes match required packaging and environmental compliance specifications before procurement.

Selection Notes

Select this component when designing optical front-ends requiring robust limiting amplification for multi-rate serial data streams. Ensure the system power budget accommodates the low-power requirements typical of SFP modules and that the 10-pin footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX3747 family of limiting amplifiers manufactured by Maxim Integrated, now part of Analog Devices. These devices are specifically engineered for high-speed optical communication links, providing signal conditioning necessary for reliable data recovery in fiber optic networks.

Replacement Considerations

The MAX3747AEUB is a verified alternative within the same family offering pin-for-pin compatibility. Verify specific electrical parameter differences between the EUB and AEUB suffixes against the official datasheet before substitution.
