Description
Applications
The Si47901/02 analog AM/FM receiver and digital radio
tuner sets a new standard for automotive broadcast
reception.
- Automotive OEM infotainment systems
- Aftermarket car radio systems
The Si47901/02 is the most integrated monolithic IC in the
industry with the smallest external bill of materials.
Si47901/02 based systems can scale from lowcost single
tuner AM/FM radio to 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 meets
rigorous automotive quality standards.
