High-Stability Si500 Provides Low Jitter and High Reliability for Consumer ApplicationsSilicon Labs leveraged its expertise designing low-jitter,
frequency-flexible timing products to develop a device capable of
replacing quartz-based oscillators with an all silicon solution,
dramatically cutting oscillator lead times from up to twelve weeks to
only two weeks. The Si500
completely eliminates the quartz resonator that must be cut and tuned
for each frequency, replacing it with an ultra-low phase noise silicon
oscillator manufactured using standard, high volume IC manufacturing
processes capable of generating any output frequency from 0.9 to 200
MHz. The devices are factory programmed and shipped to customers six
times quicker than traditional oscillators, yet offer higher performance
and reliability.
Because the Si500 relies on standard CMOS manufacturing and low cost
packaging, it is immune to the contamination issues that affect
traditional hermetically-sealed ceramic or metal-packaged XOs during
device assembly, providing superior reliability at startup and
guaranteed oscillation over the lifetime of the product. By eliminating
the mechanical resonator used for frequency generation, the Si500 also
provides high immunity to the shock and vibration that plagues
traditional crystal oscillators. The Si500 is the first silicon
oscillator in the industry to support differential clock outputs
(LVPECL, LVDS, HCSL) in addition to CMOS and SSTL formats, providing
customers added design flexibility and improved signal integrity. The
Si500 is the industry's only oscillator
supporting a dual output CMOS format mode in which a single device can
produce two output clocks at the same frequency, eliminating the need
for external clock buffers.
Using innovative, mixed-signal analog circuitry, the oscillator is
compensated for frequency variation due to operating temperature range,
initial frequency accuracy, supply voltage change and output load
change. The Si500 represents breakthrough technology as the industry's
first silicon oscillator that provides temperature stability on par with
crystal oscillators. The product family supports frequency stability
options ranging from +/-100 to +/-150 ppm, providing customers reliable
operation and drop-in compatibility with quartz-based oscillators.
"Clocks and oscillators are the heartbeat of
all electronics systems, and Silicon Labs is leveraging its key CMOS
expertise to revolutionize this industry,"
said Dave Bresemann, vice president of Silicon Labs. "The
Si500 brings Silicon Labs to the top of this market by providing
breakthrough technology to eliminate quartz-based oscillators in
consumer applications. With the introduction of the Si500 family,
Silicon Laboratories provides customers the widest selection of
oscillator and clock products to meet their timing needs."
Silicon Labs' offers a broad portfolio of highly-integrated,
high-performance timing solutions for datacom, telecom, wireless, video,
consumer and test and measurement markets. In addition to the Si500
family, Silicon Labs offers the Si5xx family of high frequency, low
jitter crystal oscillators and voltage-controlled crystal oscillators as
well as the Si53xx Any-Rate precision clocks, providing the industry's
shortest lead times, most frequency flexible, and highest performance
timing solutions. These products use optimized DSPLL®
technology to shorten cycle times and deliver outstanding jitter
performance while the eliminating the need for complex resonator
fabrication and tuning. To simplify oscillator product selection,
Silicon Labs offers a web-based utility to generate part numbers and
initiate sample requests, which may be accessed by visiting www.silabs.com/products/clocksoscillators/Pages/BuildPartNumber.aspx.
