SUNNYVALE, Calif. – November 15, 2011SiTime Corporation, an analog semiconductor company, today introduced the SiT530x family of Stratum 3 compliant silicon MEMS timing solutions that replace OCXOs and TCXOs. The SiT5301 and SiT5302 are targeted at telecom and networking infrastructure such as SONET and Synchronous Ethernet based core and edge routers, wireless base stations, IP timing and smart grid applications. The SiT530x family uniquely combines Stratum 3 stability with small size, low voltage operation and programmable features that allows customers to quickly and easily customize and differentiate their products.

SiT530x"SiTime's revolutionary technology integrates silicon MEMS and analog ICs to deliver innovative solutions. The quartz industry took decades to deliver this level of precision; SiTime, in 5 years, has broken through the same performance level. With our semiconductor expertise we have added unique features that offer additional value to the customer," said Rajesh Vashist, CEO of SiTime. "With game-changing products like the Stratum 3 clocks, and our recently announced differential oscillators and VCXOs, SiTime is accelerating the adoption of silicon MEMS timing products. SiTime is now addressing an oscillator market of $1 billion. Our remarkable combination of performance, lower cost and ease-of-use has successfully converted over 500 customers away from legacy quartz products."

"That a MEMS device can now replace OCXOs and TCXOs is a landmark that was considered unachievable for MEMS timing technology just a few years ago," said Jean-Christophe Eloy, CEO and founder of Yole Développement. "SiTime can now join a league of elite timing suppliers that service the highest performance applications. I think we can now safely say MEMS devices offer more features, higher performance and better value than quartz, which is driving the electronics industry's adoption of Silicon MEMS timing solutions."

"With the new SiT530x Stratum 3 products, SiTime continues to set new benchmarks in performance, features and reliability," said Jeff Eastman, SVP Global Marketing and Asset Management Arrow Electronics. "SiTime's programmable architecture ensures that Arrow always has SiTime products in stock. Many of our customers already enjoy the benefits of SiTime's silicon MEMS solutions today. With Arrow's large global footprint and SiTime's unique technology, we are well positioned to accelerate the proliferation of SiTime's innovative timing products into all segments of the electronics market."

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

  • Meets or exceeds Telcordia GR-1244 Stratum 3 frequency stability specifications for the most stringent timing applications
    • ±0.1 PPM frequency stability over commercial temperature (0 to 70°C)
    • <±0.37 PPM 24-hour holdover stability
    • ±4.6 PPM frequency stability over 20 years
  • Available in a 2520 compatible package, the industry's smallest ±100 PPB solution. This is a 60% reduction in size compared to any other Stratum 3 TCXO and 10 times smaller than an OCXO. The family is also available in 3225, 5032 and 7050 packages.
  • Widest frequency range of 1 to 220 MHz with 6 digits of accuracy that allows designers to easily program custom frequencies and develop systems with better performance and reliability
  • Unlike quartz, the SiT530x oscillators have no activity dips, which enable a more stable reference clock and superior system performance over temperature
  • Operating voltage of 2.5V to 3.3V supports all telecom and networking SOCs, ASICs, and FPGAs and eliminates level translation
    500 femtoseconds of typical integrated RMS phase jitter (12 kHz to 20 MHz) to meet the stringent requirements of telecom and networking applications
  • SoftEdge™ configurable rise/fall time control improves trace impedance matching and reduces EMI
  • Available voltage control with pull range of up to ±12.5 PPM for in-system calibration and fine-tuning over time
  • Outstanding silicon reliability of 500 Million hours MTBF (10 times better than quartz)
  • 50,000 g shock and 70 g vibration resistance (10 times better than quartz)

Samples will be available in December 2011 to qualified customers and production is planned for 1H2012. Pricing is available upon request.
