Description

The Si4790x analog AM/FM receiver and digital radio tuner

sets a new standard for automotive broadcast reception.

The Si4790x is the most integrated monolithic IC in the

industry with the smallest external bill of materials. Si4790x

based systems can scale from low-cost 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 Si4790x meets rigorous

automotive quality standards.

Applications

- Automotive OEM infotainment systems

- Aftermarket car radio systems
