MAX2175

RF to Bits Automotive Radio Tuner

Analog/Digital Radio Receiver Supports Remote Tuners and Software-Defined Radio


Description

The MAX2175 IC is an advanced analog/digital RF to Bits® radio receiver with front-end designed for remote tuner and software-defined radio solutions in automotive reception environments. This highly integrated tuner uses direct-conversion for digital audio broadcast (DAB) and digital multimedia broadcast (DMB) applications, covering both VHF Band-III and L-Band. Reception of FM, DRM+, FM-HD, and Weather-Band is supported using a low-IF and digital conversion to baseband. AM (long, medium and short wave) and DRM reception is supported using direct sampling and digital conversion to baseband.

The device provides a buffered differential output of the reference frequency to support multi-tuner systems. The design integrates all key blocks, enabling low-power, tuner-on-board designs with advanced baseband solutions. The tuner includes digital filtering to minimize the MIPS required in the baseband processor to demodulate the desired channel. The resulting I-channel and Q-channel data words are transferred to the baseband through an industry standard I2S digital interface.

The MAX2175 IC is available in a 48-pin TQFN package (7mm x 7mm) with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
