MAX3804ETE

Overview

The MAX3804ETE is a high-speed Ethernet transceiver designed for 12.5 Gbps data rates. It integrates a driver with an analog equalizer capable of compensating up to 20dB of loss at 5GHz. The device operates on a single 3.3V supply and features a 16-TQFN (3x3) package with exposed pad. It supports standard logic levels with a VIH minimum of 2.0V and VIL maximum of 0.8V under 3.3V operation, ensuring compatibility with specific interface requirements.

Feature Summary

• Integrates a driver with an analog equalizer to compensate signal loss
• Supports high-speed data transmission at 12.5 Gbps
• Operates on a single 3.3V power supply

Applications

• High-speed Ethernet interconnects
• Data center networking equipment
• Telecommunications infrastructure

Procurement Notes

Verify the exact part number suffix, such as +T or #G16, as these indicate specific packaging or lead-free status variations. Confirm that the input logic voltage levels match the source device capabilities, specifically noting the 2.0V VIH minimum requirement when operating at 3.3V. Ensure the PCB layout accommodates the 16-TQFN package dimensions and thermal pad requirements for proper heat dissipation.

Selection Notes

Select this component for applications requiring integrated equalization to mitigate channel loss at 5GHz. Consider the strict input voltage thresholds; it is not compatible with 2.5V logic levels directly. Evaluate the need for a 3.3V supply rail and the physical space constraints of the 3x3mm TQFN footprint. This part is suitable where settable receive equalization is necessary for signal integrity in high-speed serial links.

Part Context

The MAX3804ETE belongs to the MAX3804 family of high-speed Ethernet transceivers manufactured by Maxim Integrated, now part of Analog Devices Inc. These devices are engineered for demanding network environments requiring reliable data transmission over copper channels. The series typically includes variants with different packaging options and temperature ranges to suit various industrial and commercial deployment scenarios.
