SiTime Innovates High-Precision OCXO Timing Market with Stratum 3 Solutions

World's smallest ±100PPB oscillator, 1/10 the power consumption of an OCXO

Sunnyvale, California, USA – November 15, 2011 – SiTime Corporation, an analog semiconductor company, today launched the SiT530x family of Stratum 3-compatible silicon MEMS timing solutions to replace OCXOs and TCXOs. The SiT5301 and SiT5302 target communications and networking infrastructures such as SONET, synchronous Ethernet-based core and edge routers, wireless base stations, IP timing, and smart grid applications. The SiT530x family uniquely integrates Stratum 3 safety with a small size, low-voltage operation, and programmable features, enabling customers to quickly and easily customize and differentiate their products.

Rajesh Vashist, CEO of SiTime, stated, “SiTime’s innovative technology provides groundbreaking solutions by integrating silicon MEMS and analog ICs. While it took the quartz industry decades to achieve this level of precision, SiTime accomplished the same performance in just five years. Through our semiconductor expertise, we have added unique features that deliver added value to our customers.”
With market-changing products such as the Stratum 3 clock and our recently announced differential oscillators and VCXOs, SiTime is accelerating the adoption of silicon MEMS timing products. SiTime currently supports the $1 billion oscillator market. “We have succeeded in getting more than 500 customers to switch their existing quartz products to ours by providing an excellent combination of performance, low cost, and ease of use,” he said.

Jean-Christophe Eloy, founder and CEO of Yole Développement, said, “The fact that MEMS devices can now replace OCXOs and TCXOs is a landmark that was considered unattainable through MEMS timing technology just a few years ago.” He added, “SiTime is now able to compete with leading timing suppliers supporting high-performance applications. I believe we can now say with certainty that MEMS devices are accelerating the adoption of silicon MEMS timing solutions in the electronics industry by providing enhanced performance and superior value while offering more features than quartz.”

Jeff Eastman, Senior Vice President of Global Marketing and Asset Management at Arrow Electronics, stated, “With the new SiT530x Stratum 3 products, SiTime continues to set new benchmarks in performance, functionality, and reliability. SiTime’s programmable architecture ensures that Arrow can always maintain stock of SiTime products. Many of our customers are already leveraging the benefits provided by SiTime’s silicon MEMS solutions. Through Arrow’s global sales network and SiTime’s unique technology, we have secured a leading position in accelerating the expansion of SiTime’s innovative timing products across all sectors of the electronics market.”

The SiT530x family consists of two devices: SiT5301 operates from 1 MHz to 60 MHz, and SiT5302 operates from 60 MHz to 220 MHz. Both devices offer the following features and benefits.

• Meets or exceeds Telcordia GR-1244 Stratum 3 frequency safety for the most stringent timing applications.
o Provides ±0.1 PPM frequency stability over the operating temperature range (0°C–70°C).
o <±0.37PPM provides 24-hour continuous safety
o Provides ±4.6 PPM frequency stability for over 20 years

• It is the industry's smallest ±100 PPB solution as it is provided in a 2520 compatible package. This makes it 60% smaller than other Stratum 3 TCXOs and more than 10 times smaller than OCXOs. The product family is also available in 3225, 5032, and 7050 packages.

• It provides the widest frequency range from 1 MHz to 220 MHz with up to 6 digits of frequency accuracy, enabling designers to easily program custom frequencies and develop systems that provide enhanced performance and reliability.

• Unlike quartz, the SiT530x oscillator has no activity dip, so it supports a more stable reference clock and excellent system performance over the entire temperature range.
• Operating voltages from 2.5V to 3.3V support all communication and networking SoCs, ASICs, and FPGAs and eliminate level conversion functions.

• A typical integrated RMS phase jitter of 500fs (12kHz to 20MHz) meets the stringent requirements of communication and networking applications.

• SoftEdge™ configurable rise/fall time control improves trace impedance matching performance and reduces EMI.

• Supports voltage control functions providing a pull range of up to ±12.5 PPM for in-system compensation and precise overtime adjustment.

• Exceptional silicon reliability supporting 500 million hours of MTBF (10x improvement over quartz)
• 50,000 g shock and 70 g vibration resistance (10 times better than quartz)
• 50,000g shock and 70g vibration resistance (10x improvement over quartz)

Samples are currently being provided to certified customers, and mass production is scheduled for December 2011. Price information can be provided separately upon request.
