Maxim Integrated MAX2171ETL+T RF to Bits Tuner

The MAX2171ETL+T from Maxim Integrated is a state-of-the-art RF to Bits® tuner designed for use in digital audio broadcasting (DAB) applications, including DAB, DAB+, and T-DMB. This advanced tuner component is part of Maxim's commitment to providing high-performance, compact, and power-efficient solutions for the rapidly evolving automotive and consumer electronics markets.

With its highly integrated design, the MAX2171ETL+T simplifies the development of digital radio systems by converting RF signals directly to digital I/Q data. This tuner supports the extended VHF III band from 168MHz to 240MHz, L-band from 1452MHz to 1492MHz, and Band III from 174MHz to 240MHz, making it versatile for various regional standards and frequency ranges.

Equipped with a built-in digital filtering and decimation feature, it effectively reduces the output data rate to a manageable level for downstream processing. The MAX2171ETL+T also integrates an RF tracking filter, LNA, mixers, LO generation with VCO, digital conversion, and filtering, all within a compact 40-pin TQFN package (6mm x 6mm). This level of integration not only saves board space but also reduces the external component count, which can lead to cost savings and a more reliable end product.

The device operates over a -40°C to +85°C temperature range, making it suitable for the harsh environments typically found in automotive applications. Additionally, the MAX2171ETL+T features an I²C interface for configuration and control, allowing for easy integration into existing digital radio designs.

Maxim Integrated's MAX2171ETL+T is an ideal solution for designers looking to implement digital radio functionality with minimal design complexity and maximum performance. Whether it's for in-car entertainment systems, portable radios, or other DAB-enabled applications, this RF to Bits tuner offers a high level of integration and performance to meet the needs of modern digital radio systems.
