AUSTIN, Texas -- Silicon Laboratories Inc. (NASDAQ: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced its entry into the consumer timing market with the introduction of the industry’s highest stability 100 percent CMOS oscillator, offering a replacement for crystal oscillators (XOs) with shorter lead times, lower cost, higher reliability and higher performance. The new Si500 family has the widest frequency range, widest selection of differential and single-ended clock formats, low total power consumption and the lowest jitter of any oscillator targeted at high volume consumer applications. This combination provides an unprecedented level of flexibility to designers of applications such as digital still cameras, camcorders, printers, PC peripherals, LCD displays, servers and storage applications.

Silicon 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.”
