MAX2172ETL+T

Overview

The MAX2172ETL+T is a direct-conversion to low-IF tuner for DTV applications. It integrates RF and IF sections in a single chip, supporting multiple frequency bands including 87MHz–108MHz, 168MHz–240MHz, and 1.452GHz–1.492GHz. The device utilizes a 40-TQFN (6x6) package with an exposed pad for thermal management.

Feature Summary

• Combines direct-conversion and low-IF architectures for efficient signal processing
• Integrates complete RF and IF sections within a single chip solution
• Supports multiple broadcast standards through flexible frequency tuning

Applications

• Digital television receiver systems
• Satellite TV tuners
• Cable TV front ends

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for recent production change notices. Ensure the specific suffix matches design requirements, as packaging variations may exist.

Selection Notes

Evaluate the trade-off between direct-conversion simplicity and low-IF image rejection capabilities. Consider the 40-TQFN package constraints for PCB layout and thermal dissipation. Verify that the integrated gain and noise figure meet system sensitivity requirements for the target frequency band.

Part Context

This component belongs to the MAX2172 series of tuners designed for digital video applications. It represents a highly integrated solution aimed at reducing bill-of-materials costs and board space in consumer electronics by combining multiple functional blocks into one package.

Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume pin-to-pin compatibility with other tuner families without explicit datasheet confirmation.
