AUSTIN, Texas -- March 27, 2013

Silicon Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced the latest generation of the company’s
widely used analog-tuned, analog/digital-display (ATxD) multiband radio IC
family. The new Si4825/27/36 AM/FM/SW receivers provide superior radio band
coverage and a 16-pin SOIC package option that eases the design and
manufacturing of ATxD radio products. The new Si48xx radio ICs provide an
“all-in-one” single-chip receiver solution for tabletop and portable radios,
stereos, mini/micro systems, boomboxes, clock radios, iPod docking stations,
toy radios and many other consumer products containing wheel-tuned radios.

The wheel-tuned or “analog-tuned” multiband radio product market exceeds 115
million units per year, according to Silicon Labs estimates. More than 90
percent of all ATxD radios including products for the global export market are
manufactured in China. A pioneer in RF-in-CMOS multiband receivers for the
wheel-tuned radio market, Silicon Labs has now delivered three generations of
single-chip receiver solutions that reduce the cost and complexity and
simplify the manufacturing of radio products used by many millions of
consumers worldwide.

Silicon Labs’ new Si4825/27/36 receivers offer the same exceptional RF
performance, unmatched integration in CMOS, bill of materials (BOM) and labor
cost reduction, and ease of design and manufacturing as previous generations
of Si48xx radio ICs. In addition, the new receivers use a single band to cover
a wider frequency range for FM and SW bands, and they also support TV audio
carrier reception in the China market. Additionally, the devices provide
advanced audio conditioning for all signal environments, removing pops, clicks
and loud static in challenging signal conditions.

The Si4825 mono-output, consumer-grade product and the Si4836 stereo-output,
commercial-grade product are designed for the ATAD radio market. The Si4827
mono-output, consumer-grade product targets the ATDD radio market. Each
receiver supports worldwide broadcast frequencies from 64-109 MHz in FM,
504-1750 kHz in AM and 2.3-28.5 MHz in shortwave (SW), enabling a single radio
design based on the receivers to support all worldwide markets.

“Silicon Labs’ Si48xx multiband receiver family provides an innovative
‘radio-on-a-chip’ architecture that enables wheel-tuned radio manufacturers to
simplify and shrink their board designs, eliminate costly manual labor in
manufacturing and reduce component count by more than 80 percent,” said James
Stansberry, vice president and general manager of Silicon Labs’ broadcast
products. “Our new wheel-tuned receivers leverage the patented low-IF digital
architecture, digital core and audio conditioning technology used in our most
advanced radio IC products adopted by Tier 1 audio product brands around the
