Si4790x Automotive Tuners

 

The Si4790x analog AM/FM receiver and digital radio tuner family sets a new standard for automotive broadcast reception. The Si4790x family are the most integrated monolithic ICs 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.
