Si4730/31/34/35-D60
BROADCAST AM/FM/SW/LW RADIO RECEIVER
Features
Applications
Description
The Si473x-D60 digital CMOS AM/FM radio receiver IC integrates the complete
tuner function from antenna input to digital audio output and includes a stereo
audio AUXIN ADC input for converting analog audio into standard I2S digital
audio, enabling a cost efficient digital audio platform for consumer electronic
applications with high TDMA noise immunity, superior radio performance, and
high fidelity audio power amplification. When enabling the analog inputs in stereo
AUXIN ADC-mode, the Si473x-D60 supports I2S digital audio output only (no
analog output).
