Introduction

The FSV473x digital CMOS AM/FM radio receiver IC integrates the complete tuner function from antenna input to digital audio output and includes a stereo audio 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, the FSV473x supports I2S digital audio output only (no analog output).
