Introduction

The Si47951/52 analog AM/FM receiver and digital radio tuner sets a new standard for automotive broadcast reception. The Si47951/52 is the most highly integrated automotive tuner in the industry with a minimal external BOM. Systems based on the Si47951/52 can scale from low-cost single-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 using a common software API. The Si47951/52 Grade A components comply with stringent automotive quality standards.
