Si4704/05 FM Radio Receivers
The Si4704/05 enhanced FM receiver family is the most advanced portable solution available today offering digital audio out, worldwide FM band support, and highly flexible and proven FM functionality in a simple API.
The Silicon Labs Si4705 IC offers digital audio out for FM recording. The content can also be tagged with RDS information, allowing song name and artist labels to be displayed similar to MP3 meta data. Using the digital audio out, the Si4705 can also reduce total system power consumption by avoiding unnecessary ADC/DAC conversions between the FM receiver and the host processor.
