Introduction

The Si47971/72 integrates two worldwide radio receivers with audio processing functionality. The analog AM/FM receiver and digital radio tuner set a new standard for automotive broadcast reception. The integrated audio processing subsystem provides a complete solution for synchronizing, processing, aggregating, and distributing digital and analog audio signals within a head unit. The Si47971/72 is the most highly integrated automotive tuner in the industry, with the smallest external BOM. Systems based on the Si47971/72 can scale from low-cost dual-tuner AM/FM radios to high-performance systems with multiple tuners and multiple antennas, enabling radio suppliers to reuse their R&D investment across multiple product lines — all through a common software API. The Si47971/72 Grade A components meet stringent automotive quality standards.
