MAX3746HETE#G16

Overview

The MAX3746HETE#G16 is a single-channel limiting amplifier IC from the Maxim Integrated portfolio, designed for high-speed optical receiver applications. It operates within a supply voltage range of 2.97 V to 3.63 V and draws a typical operating current of 35 mA. The device supports data rates from 622 Mbps to 3.2 Gbps and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in a compact 16-TQFN (3x3 mm) surface-mount format with an exposed pad, it dissipates up to 1.4 W of power. This component serves as a critical interface stage for converting optical signals into electrical logic levels.

Feature Summary

• Provides signal conditioning and amplification for high-speed serial data streams
• Supports multiple standard data rates including OC-12 and STM-4 speeds
• Integrated design reduces external component count for receiver front-ends

Applications

• Optical fiber communication receivers
• SONET/SDH network equipment
• High-speed serial data links

Procurement Notes

Verify the specific suffix #G16 against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with Analog Devices, as legacy parts may have varying environmental declarations. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like the ETE version.

Selection Notes

Select this component when designing optical receivers requiring amplification between 622 Mbps and 3.2 Gbps. The 16-TQFN package is suitable for space-constrained PCB layouts. Verify that the system power supply can maintain the required 3.3 V nominal voltage within the specified tolerance range for stable operation.

Part Context

This part belongs to the MAX3746 series of limiting amplifiers, widely used in telecommunications infrastructure. It complements other Maxim integrated circuits such as laser drivers and transimpedance amplifiers to form complete optical transceiver modules. The series is known for robust performance in SONET/SDH environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult the manufacturer's official obsolescence notices or cross-reference guides for validated alternatives.
