Description
Applications
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.
