Introduction

The Si47901/02 is the most integrated automotive tuner in the industry with the smallest external bill of materials. Si47901/02 based systems can scale from a low-cost single tuner AM/FM radio to the highest performance systems with multiple tuners and multiple antennas, enabling the radio suppliers to reuse their R&D across multiple product lines, all with a common software API. The Si47901/02 A-grade parts meet rigorous automotive quality standards.
