Maxim Integrated MAX2173ETL RF to Bits® Tuner

The MAX2173ETL from Maxim Integrated is a highly integrated RF to Bits® tuner designed for use in digital audio broadcast (DAB) systems, including DAB, DAB+, and T-DMB applications. It is part of Maxim's advanced line of radio tuners that deliver high performance while simplifying system design by integrating several key functions into a single chip.

This versatile tuner supports the 168MHz to 240MHz Band III, the 1452MHz to 1492MHz L-Band, and the 76MHz to 108MHz FM band. Its innovative architecture allows for direct conversion of RF signals to digital bits, which significantly reduces the complexity of subsequent processing stages.

The MAX2173ETL is equipped with a high-performance on-chip RF amplifier, which ensures excellent sensitivity and dynamic range. The device features an integrated digital filtering and decimation stage, which simplifies the interface to the host processor and reduces the demand on system resources. Its I2S output interface is designed for seamless integration with most modern digital signal processors (DSPs) and microcontrollers.

With its low power consumption and small footprint, the MAX2173ETL is an ideal choice for both portable and automotive applications where space and power efficiency are critical. The device is housed in a compact 40-pin TQFN package, which makes it suitable for space-constrained environments.

Key features of the MAX2173ETL include:

• Direct RF to Bits conversion
• Support for multiple broadcast bands
• Integrated RF amplifier and digital filtering
• Low power consumption
• Compact 40-pin TQFN package
• I2S digital output for easy interfacing

The MAX2173ETL provides a robust and efficient solution for developers looking to incorporate digital radio functionality into their products. With its high level of integration and ease of use, the MAX2173ETL helps to accelerate time-to-market for a wide range of applications.
