Si4704/05
Enhanced Broadcast FM Radio Receiver for Portable Applications
Description
The Si4704/05 enhanced FM receiver is the most
advanced portable solution available today offering
embedded antenna support, digital audio out, worldwide
FM band support, and highly flexible, mature, and proven
FM functionality in a simple API. The Si4704/05
incorporates Silicon Labs' tuned-resonance antenna
technology for crystal clear FM reception in wire-free
device enclosures. Silabs' internationally patented tuned-
resonance technology allows embedded FM antennas
such as PCB traces, loops, stubs, or other devices to
perform exceptionally well, enabling devices with
integrated Bluetooth to receive FM transmissions without
an external FM antenna, and transmit the FM content to
Bluetooth-enabled headsets. This is the best, most cost-
effective solution to enable wire-free FM reception.
The Si4705 also offers digital audio out for FM recording.
Content recorded over the Si4705 can be shared with
friends or played at a later time in MP3 format. The content
can also be tagged with RDS information, allowing song
name and artist labels to be displayed as is done with 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.
The Si4704/05 truly supports worldwide FM bands, starting
at 64 MHz for Eastern European countries and extending
all the way to 108 MHz for the rest of the world. The device
supports channel spacing down to 10 kHz, and includes
advanced, proven seek functionality. All the Silicon Labs
proven FM receiver expertise is incorporated in the Si4704/
05, gained through thousands of designs with almost every
OEM and ODM in the world and over 100 million devices
shipped.
The Si4704/05 leverage Silicon Labs' internationally
patented and proven digital low-IF architecture, offering
proven functionality in a simple and mature API. The
device is offered in a highly reliable, ultra-small
3 x 3 x 0.55 mm 20-pin QFN and is layout compatible with
the full suite of Silicon Labs broadcast offerings including

board area, or less than half that of other
competing solutions. The Si4705 incorporates Silicon Labs'
proven and widely adopted RDS processor, including
worldwide compliance, all symbol decoding, error
detection, error correction, and other RDS functions. The
Si4705 RDS functionality is unmatched in the industry for
performance, on-chip processing, and worldwide adoption.
