High-Performance Timing Solutions Reduce Electro-Magnetic Interference While Delivering the Widest Frequency Range and Lowest Jitter

SUNNYVALE, Calif.November 3, 2008 – SiTime Corporation, the leader in MEMS-based silicon timing solutions, today introduced a new family of programmable spread spectrum clock oscillators that are the smallest in the industry and offer the widest frequency range and lowest cycle to cycle jitter. The first solutions in this high-performance product line include the SiT9001, which offers the industry’s smallest footprint for space constrained applications, and the SiT9002, the only differential output programmable spread spectrum clock oscillator on the market today. Both devices include an embedded MEMS resonator as the clock reference, which eliminates the need for external components.

“Our new spread spectrum oscillators are drop-in replacements for standard oscillators, which will help our customers to eliminate expensive delays in development and bring their products to market faster,” said Piyush Sevalia, vice president of marketing at SiTime. “These programmable MEMS-based oscillators enable users to reduce electro-magnetic interference (EMI) and pass environmental testing without the need to redesign their boards or use expensive metal enclosures.”

The SiT9001 is available in a standard footprint four-pad 2.5 x 2.0 mm package, the smallest in the industry for spread spectrum oscillators. The device also is available in larger, standard-footprint surface-mount packages that can replace existing oscillators without an expensive board redesign. The solution delivers unmatched flexibility with a programmable frequency range of 1 MHz to 200 MHz and programmable operating voltages of 1.8V, 2.5V or 3.3V. In addition, it has the industry’s lowest cycle to cycle jitter – less than 30 ps – ensuring adequate system timing margin and compatibility with a wide variety of applications.

The SiT9002 is optimized for high-performance networking and computing applications and offers low voltage differential signaling (LVDS), low voltage positive emitter coupled logic (LVPECL) and current mode logic (CML) outputs. The device is available in six pad, 5.0 x 3.2 mm and 7.0 x 5.0 mm packages, which are compatible with industry-standard footprints.  The SiT9002 is programmable, with a frequency range from 10 MHz to 220 MHz and programmable operating voltages of 1.8V, 2.5V or 3.3V. It offers frequency tolerance of 25 PPM or 50 PPM when spread spectrum is turned off. And, like the SiT9001, the device delivers cycle to cycle jitter of less than 30 ps.

Both the SiT9001 and SiT9002 use SiTime’s proven MEMS technology to offer 10 times better robustness and reliability than existing, quartz-based solutions, supporting longer-life electronics. The devices’ programmability also allows delivery of samples in 24 to 48 hours and production quantities in two to three weeks.

The SiT9001 is currently available in production quantities. The SiT9002 will begin sampling in December 2008, with production expected by February 2009. Pricing is available upon request.
