MAX2170ETL/V+

Overview

The MAX2170ETL/V+ is a direct-conversion to low-IF tuner designed for Digital Audio Broadcast (DAB) applications. It integrates a Sigma-Delta fractional-N synthesizer and operates within a frequency range of 87 MHz to 1492 MHz. The device requires a supply voltage between 2.7 V and 3.5 V. It is housed in a 40-pin WFQFN exposed pad package with surface mount mounting type. This component supports AEC-Q100 standards, indicating suitability for automotive environments.

Feature Summary

• Integrates direct-conversion and low-IF tuning architectures for DAB reception
• Includes an on-chip Sigma-Delta fractional-N synthesizer
• Supports wide frequency coverage from 87 MHz to 1492 MHz

Applications

• Digital Audio Broadcast (DAB) receivers
• Broadcast radio systems
• Automotive infotainment tuners

Procurement Notes

Verify the specific suffix 'V+' against the official Analog Devices datasheet to confirm package type and temperature grade. Check current product status as some variants may be discontinued or subject to supply constraints. Ensure compatibility with existing board layouts due to the 40-WFQFN package dimensions.

Selection Notes

Select this component for designs requiring integrated DAB tuning with minimal external passive components. Consider the 40-pin QFN footprint for space-constrained applications. Verify power supply requirements align with the 2.7 V to 3.5 V operating range. Confirm AEC-Q100 qualification if deploying in automotive contexts.

Part Context

This part belongs to the MAX2170 series of RF tuners by Analog Devices/Maxim Integrated. It serves as a specialized solution for digital broadcast reception, combining RF front-end functionality with synthesizer generation in a single chip.

Replacement Considerations

Consult the official discontinuance notification or cross-reference list from Analog Devices for verified substitutes. Generic RF tuners may not match the specific DAB architecture or synthesizer integration.
