MAX3654ETE+T

Overview

The MAX3654ETE+T is an analog transimpedance amplifier (TIA) designed for CATV applications in fiber-to-the-home networks. It operates from 47MHz to 870MHz, supporting subcarrier multiplexed signals in passive optical networks. The device features a gain-control input for AGC operation with optical inputs ranging from -6dBm to +2dBm average power. It provides a maximum gain of 62dB at 47MHz and an 18dB gain control range. Powered by a single +5V supply, it dissipates 700mW and functions within a temperature range of -40°C to +85°C.

Feature Summary

• High-linearity amplification for analog PIN photocurrent conversion to 75Ω CATV output
• Integrated automatic gain control support via dedicated gain-control input
• Compact 4mm x 4mm TQFN package integrating all active RF circuitry

Applications

• FTTH Optical Network Termination (ONT)
• Passive optical network (PON) signal processing
• CATV subcarrier multiplexed signal reception

Procurement Notes

Verify the specific suffix 'E+T' against the manufacturer's official datasheet to confirm pinout, packaging, and RoHS compliance status. Ensure the component matches the required operating temperature range and voltage specifications for your design. Cross-reference the part number with current availability notices as discontinuation or lifecycle changes may affect sourcing options.

Selection Notes

Select this component when designing FTTH ONT systems requiring high linearity and wide bandwidth up to 870MHz. The integrated gain control simplifies AGC implementation for varying optical input levels. Consider the 700mW power dissipation and thermal management requirements associated with the compact TQFN package during PCB layout.
