AUSTIN, Texas--(BUSINESS WIRE)--Jan. 22, 2007--Silicon
Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance,
analog-intensive, mixed-signal ICs, today announced the extension of
its broadcast audio product portfolio to include the Si473x AM/FM
receiver family. The Si473x enables an AM/FM receiver to be easily
added to consumer devices such as clock and portable radios, home
stereos, MP3 players, docking stations and mobile handsets.
The Si473x is the first fully integrated AM/FM radio receiver from
antenna input to audio output in a single monolithic IC. Conventional
AM/FM radio implementations are large, expensive and difficult to
manufacture, limiting the inclusion of AM radio functionality in many
small, portable, high-volume applications. The single-chip Si473x
requires only two external components in 0.15 cm(2) of board space
compared to more than 50 components and 10 cm(2) of board space for
conventional solutions.
By leveraging an innovative digital architecture, the Si473x
significantly simplifies design and manufacturing. The Si473x is the
only AM/FM receiver that does not need manual alignment, which can
take up to several minutes per device. While traditional AM/FM
solutions may require four stages of hand tuning, the Si473x supports
a wide variety of antennas with an on-chip varactor and auto
calibration to streamline manufacturing.
The Si473x seek performance and adjustability for both AM and FM
is unmatched, resulting in reduced interference and improved
reception. The excellent sensitivity and selectivity of the Si473x
reliably identify many stations other AM/FM radios do not detect or
incorrectly identify as valid. The market-leading audio quality of the
Si473x offers adjustable soft mute and other audio enhancement
features.
The Si4731 is also the only AM/FM receiver to include support for
the European Radio Data System (RDS) and the U.S. Radio Broadcast Data
System (RBDS). This feature enables data such as the station ID and
song name to be displayed on the LCD of any device, creating a visual
user experience similar to that of a portable media player.
"AM radio is popular for music, news, sports and talk formats, has
a wide coverage area and a large installed base of stations
worldwide," said Tyson Tuttle, vice president of Silicon Laboratories.
"We have leveraged our market-leading CMOS RF and mixed-signal
expertise to engineer an easy-to-design, cost-effective,
high-performance solution, which will enable manufacturers to offer
both AM and FM receivers in a variety of applications including mobile
handsets and MP3 players."
Pricing and Availability
Samples of the Si4730 and Si4731 are available in a compact 3x3 mm
20-pin quad flat no-lead (QFN) package. Pricing for the Si4730 begins
at $4.87 in quantities of 10K. Pricing for the Si4731, which supports
RDS/RBDS, begins at $5.53 in quantities of 10K. An evaluation board is
available for $150.
