  Silicon Labs Introduces the Industry’s First Single-Die MEMS Oscillator

 New Si50x CMEMS® Oscillators Leap Ahead of Quartz-Based Timing Devices with
        Superior Frequency Stability, Reliability and Programmability

Business Wire

AUSTIN, Texas -- June 26, 2013

Silicon Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced the industry’s most highly integrated
MEMS-based oscillators designed to replace general-purpose crystal oscillators
(XOs) in cost-sensitive, low-power and high-volume industrial, embedded and
consumer electronics applications such as digital cameras, storage and memory,
ATM machines, point-of-sale equipment and multi-function printers. The new
Si50x oscillators are based on Silicon Labs’ patented CMEMS® technology – the
first to enable MEMS structures to be built directly on top of standard CMOS
wafers in high-volume fabs, resulting in fully integrated, highly reliable
monolithic “CMOS+MEMS” IC solutions.

Silicon Labs’ Si50x CMEMS oscillator family achieves smaller size, higher
reliability, better aging and higher integration than existing frequency
control solutions through a patented monolithic architecture that integrates
the MEMS resonator together with the CMOS oscillator circuitry on a single
die. The benefits of this unprecedented CMOS+MEMS integration combined with
Silicon Labs’ proven mixed-signal expertise are transformational for the
frequency control industry:

  *CMEMS oscillators are manufactured in a high-volume CMOS fab with unified
    foundry lines that support wafer probing of complete oscillator systems
    for state-of-the-art quality and process control.
  *CMEMS technology enables guaranteed data sheet performance with 10 years
    of frequency stability including solder shift, load pulling, V[DD]
    variation, operating temperature range, vibration and shock. This
    guaranteed operating life performance is 10 times longer than typically
    offered by comparable crystal and MEMS oscillators.
  *CMEMS oscillators tightly couple the MEMS resonator with CMOS temperature
    sensor and compensation circuitry, ensuring a highly stable frequency
    output in the face of thermal transients and over the full industrial
    temperature range. The end result is a predictable, reliable frequency
    reference over the long operating lifespans of industrial and embedded
    applications.
  *CMEMS resonators are passively compensated, using materials with
    offsetting temperature behaviors in the design. This enables Silicon Labs
    to apply its innovative mixed-signal circuit design expertise to create
    smaller, lower power and more cost-effective oscillators while ensuring
    excellent frequency and temperature stability and aging performance.

The Si50x CMEMS oscillators support any frequency between 32 kHz and 100 MHz.
Frequency stability options include ±20, ±30 and ±50 ppm across extended
commercial (-20 to 70 ^oC) and industrial (-40 to 85 ^oC) operating
temperature ranges. The CMEMS oscillators also offer extensive field- and
factory-programmable features including low-power and low-period jitter modes,
programmable rise/fall times and polarity-configurable output-enable
functionality.

The Si50x CMEMS oscillator family frees customers from supply chain problems
that are typical for traditional quartz-based solutions. The Si50x oscillators
are manufactured at Semiconductor Manufacturing International Corporation
(SMIC), one of the world’s leading semiconductor foundries and the largest,
most advanced foundry in mainland China. This strategic foundry relationship
increases manufacturing and supply predictability through the benefits of
massive scale and quality control. Because CMEMS oscillators are integrated,
monolithic ICs, they are packaged in widely produced, molded-compound 4-pin
packages, again ensuring a predictable and reliable supply chain.

“The timing market has reached an inflection point in which the
latest-generation MEMS-based oscillators are capable of providing reliable,
cost-effective replacements for traditional crystal oscillators,” said Jeremie
Bouchaud, director and senior principal analyst, MEMS and Sensors, IHS.
“Silicon Labs’ CMEMS technology provides the most integrated crystal
replacement solution to date by combining the MEMS resonator and frequency
control circuitry into a single-die device optimized for high-volume
electronic system designs.”

Like all Silicon Labs oscillator products, the Si50x oscillators are available
for web-based customization with short two week sample lead times or
optionally available with “0-day” lead time via instantaneous field
programming at the customer’s site by Silicon Labs’ sales channel partners. In
addition, the Si50x oscillators are pin- and footprint-compatible with
existing quartz or MEMS oscillators, enabling a quick, easy drop-in
replacement solution.

The Si50x family includes four products that enable thousands of flexible
timing configurations:

  *Si501 single-frequency oscillator with output-enable (OE) functionality
  *Si502 dual-frequency oscillator with OE and frequency-select (FS)
    functionality
  *Si503 quad-frequency oscillator with FS technology
  *Si504 fully programmable oscillator supporting all potential configuration
    features with a 1-pin interface for fine-tuned frequency adjustments
    measured in parts per billion

“The Si50x CMEMS oscillator family introduces an important technological step
forward in the frequency control market, combining all the manufacturing
advantages of a single-die MEMS-based solution while retaining some of the
best characteristics of general-purpose crystal oscillators and improving on
both reliability and lead times,” said Mike Petrowski, vice president and
general manager of Silicon Labs’ timing products. “By leveraging Silicon Labs’
expertise in MEMS design, device and process integration and mixed-signal
technology, the Si50x family provides a best-in-class general-purpose
oscillator solution for cost- and power-constrained embedded, industrial and
consumer electronics applications.”
