AUSTIN, Texas -- April 22, 2013

Silicon Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced the industry’s first single-die
antenna-input-to-audio-output digital radio receiver solution developed for
the global portable and consumer electronics markets. Leveraging
software-defined radio technology, the new monolithic Si468x receiver ICs
bring FM, HD Radio™ and DAB/DAB+ broadcast capabilities to a wide range of
audio applications, from price-sensitive clock and tabletop radios to
mainstream mini/micro audio systems and CD boomboxes to high-end multimedia
devices with displays such as mobile phones, tablets and personal navigation

Digital radio technology is the next generation of radio broadcasting. In
addition to providing better audio quality than traditional AM/FM radio,
digital radio can transmit program information, weather forecasts, news
headlines, music artist and track names, traffic information and other data.
Digital radio adoption has been slow due in part to the high cost of
delivering a high-performance yet power-efficient RF solution for the consumer
electronics market. Silicon Labs’ Si468x family directly addresses the
consumer digital radio market by providing an advanced, single-die solution
that reduces system complexity, bill of materials (BOM) count and power
consumption without compromising RF performance.

Leveraging Silicon Labs’ proven low-IF digital receiver architecture, the
Si468x family delivers superior RF performance compared to existing
consumer-grade digital radio solutions. The Si468x receivers support
auto-calibrated digital tuning and FM seek functionality based on multiple
signal quality and band parameters and provide flexible audio processing
features including noise blanking, configurable FM soft mute, FM de-emphasis
and FM hi-cut filtering.

The Si468x family enables developers to reduce system cost, size and
complexity by integrating most of the external components needed to build a
digital radio receiver system including the RF tuner, baseband and stereo
audio DACs. The family’s wafer-level chip-scale package (WLCSP) option
supports very compact designs, enabling a complete digital radio receiver
system with only 12 external components to be implemented in less than 100
square millimeters.

The Si468x receivers are engineered with small form factor designs in mind. By
integrating the RF tuner and baseband functions on a single die, the Si468x
family avoids radio self-interference and streamlines system design,
validation and testing. High integration simplifies board layout, reduces
board space requirements and enhances system stability, making the receivers a
good fit for on-board and small form factor designs where performance, size
and reliability are critical considerations. Offering the smallest footprint
and lowest power consumption of any digital radio solution on the market (less
than 60 mW in analog FM mode and less than 95 mW in HD Radio and DAB/DAB+
modes), the Si468x receivers are also an ideal choice for power- and
space-sensitive portable applications.

“Digital radio is the next wave of the broadcast audio industry, enabling
CD-quality sound for radio listeners and a host of innovative broadcast data
services,” said James Stansberry, vice president and general manager of
Silicon Labs’ broadcast products. “We’ve responded to the needs of the global
digital radio market by developing a ‘digital-radio-on-a-chip’ solution that
enables developers to reduce implementation costs and simplify their portable
and home audio product designs while delivering the highest RF performance and
sound quality to consumers.”

The Si468x receivers support worldwide analog FM radio reception and
incorporate an integrated decoder for the European Radio Data System (RDS) and
North American Radio Broadcast Data System (RBDS) standards including required
symbol decoding, block synchronization, error detection and error correction
functions. The Si468x family includes the first truly monolithic digital radio
receiver ICs certified by iBiquity to support the HD Radio standard for
portable and consumer electronics applications. The Si468x receiver family is
compatible with the European Eureka 147 DAB and DAB+ standards and is designed
to be fully compliant with the United Kingdom’s Minimum Specifications for DAB
and DAB+ Personal and Domestic Digital Radio Receivers.

Pricing and Availability

Samples and production quantities of the Si468x digital radio receivers are
available now in two package options: a 7 mm x 7 mm 48-pin QFN package and a
tiny 3.2 mm x 3.8 mm WLCSP package that is ideal for portable and
space-constrained designs. Pricing for the Si468x receiver family begins at
$5.62 (USD) in 10,000-unit quantities. To ease digital radio system design
based on the Si468x family, Silicon Labs offers comprehensive evaluation kits
priced at $550.00 (USD MSRP). For more information about Silicon Labs’ Si468x
