1 / 44 page  Rev. 1.1 11/11 Copyright © 2011 by Silicon Laboratories Si473x-D60 Si4730/31/34/35-D60 B ROADCAST AM/FM/SW/LW R ADIO R ECEIVER 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).
