Si4730/31
Broadcast AM/FM Radio Receiver
Description
The Si4730/31 is the industry's first fully integrated, 100%
CMOS AM/FM radio receiver IC. The Si4730/31 AM/FM
radio provides the space savings and low power
consumption necessary for portable devices while
delivering the high performance and design simplicity
desired for all AM/FM solutions. Offering unmatched
integration and PCB space savings, the Si4730/31
requires only two external components and less than 15
mm
2
of board area.
Leveraging Silicon Laboratories' proven and patented
Si4700/01 FM digital receiver architecture, the Si4730/31
delivers superior RF performance and interference
rejection in both AM and FM bands. The high integration
and complete system production test simplifies design-in,
increases system quality, and improves manufacturability.
The Si4730/31 solution includes advanced seek
algorithms, adjustable soft mute, auto-calibrated digital
tuning, and FM stereo processing. In addition, the Si4730/
31 provides a programmable reference clock, I
2
C-
compatible 2-wire control interface, and a Si4700/01
backwards-compatible 3-wire control interface.
The Si4730/31 utilizes digital processing to achieve high
fidelity, optimal performance, and design flexibility. The
chip provides excellent pilot rejection, selectivity, and
unmatched audio performance, and offers both the
manufacturer and the end-user extensive programmability
and flexibility in listening experience.
The Si4731 incorporates a digital processor for the
European Radio Data System (RDS) and the North
American Radio Broadcast Data System (RBDS)
including all required symbol decoding, block
synchronization, error detection, and error correction
functions. Using this feature, the Si4731 enables
broadcast data such as station identification and song
name to be displayed to the end user.
