MAX2871ETJ+T

Overview

The MAX2871ETJ+T is a fractional and integer-N synthesizer with an integrated voltage-controlled oscillator (VCO) designed for general-purpose RF applications. It operates within a frequency range of 23.5 MHz to 6000 MHz. The device supports a supply voltage between 3.14 V and 5.5 V, with a typical operating current of 144 mA at 3.3 V. It is housed in a 32-lead TQFN package with an exposed pad, rated for operation from -40°C to +85°C.

Feature Summary

• Integrates a fractional and integer-N phase-locked loop with a built-in VCO for compact system design.
• Supports ultra-wideband frequency synthesis covering ranges from 23.5 MHz up to 6 GHz.
• Features low power consumption suitable for portable and battery-operated wireless systems.

Applications

• Local oscillator generation for 5G infrastructure
• Clock generation for data converters
• General-purpose RF transceiver front ends

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure the supplier provides valid traceability for Analog Devices/Maxim Integrated components.

Selection Notes

Select this component for designs requiring a wide tuning range without external VCOs. Compare against the MAX2870 for similar functionality. Evaluate power budget constraints against the 144 mA typical current draw. Verify that the 32-TQFN footprint matches the PCB layout requirements.

Part Context

This part belongs to the MAX287x family of synthesizers from Maxim Integrated, now part of Analog Devices. It serves as a high-performance solution for generating stable local oscillator signals in modern communication systems. The ETJ+ designation specifies the lead-free, tape-and-reel variant of the standard MAX2871ETJ.
