The Si473x-D60 digital CMOS AM/FM radio receiver IC integrates the complete
broadcast tuner and receiver function from antenna input to digital audio output.
The device leverages the Silicon Labs broadcast proven digital low-IF
architecture, enabling a cost-effective, digital audio platform for consumer
electronic applications with high TDMA noise immunity, superior radio
performance, and high fidelity audio power amplification.
