Description
The Si47911/12 integrates global radio receiver with audio
processing. The analog AM/FM receiver sets a new standard
for automotive broadcast reception. The integrated audio
Applications
- Automotive OEM infotainment systems
- Aftermarket car radio systems
processing sub-system provides
a complete solution to
synchronize, process, aggregate and distribute digital and
analog audio signals in the head-unit.
The Si47911/12 is the most integrated monolithic IC in the
industry with the smallest external bill of materials. Si47911/12
based systems can scale from low-cost single tuner AM/FM
radio to the highest performance systems with multiple tuners
and multiple antennas, enabling radio suppliers to reuse R&D
across multiple product lines, all with a common software API.
The Si47911/12 meets rigorous automotive quality standards.
