Overview
The MAX2172ETL/V+ is a direct-conversion to low-IF tuner designed for digital television (DiTV) applications. It supports multiple frequency bands including FM radio (87MHz–108MHz), VHF TV (168MHz–240MHz), and UHF TV (1.452GHz–1.492GHz). The device integrates a high-performance mixer, local oscillator, and baseband filters within a compact 40-pin TQFN package measuring 6x6 mm. This integration facilitates simplified PCB layout and reduced component count in receiver designs.
Feature Summary
- Integrates direct-conversion and low-IF architecture for flexible signal processing
- Supports multi-band reception covering FM, VHF, and UHF television frequencies
- Consolidates RF and baseband functions into a single compact IC
Applications
- Digital television receivers
- FM radio tuners
- VHF/UHF TV set-top boxes
Procurement Notes
Verify availability status as the component may be subject to limited supply or factory special orders. Confirm that the ordering suffix corresponds to the specific package variant required. Ensure compatibility with existing design specifications before procurement. Check for alternative sources if standard distribution channels indicate non-stock status.
Selection Notes
Select this tuner for applications requiring integrated support for FM, VHF, and UHF bands. Consider the 40-TQFN package dimensions for board space constraints. Evaluate the direct-conversion architecture against system noise requirements. Verify power supply voltage levels match the datasheet specifications.
