SiTime Expands Product Portfolio with Industry's First Kilohertz (kHz) Silicon MEMS Oscillator Launch
Suitable for audio, microcontroller, and industrial applications due to programmability, miniaturization, and robustness

Sunnyvale, California, September 27, 2010 – SiTime, a leader in silicon MEMS timing solutions, today launched the industry's first kilohertz (kHz) silicon MEMS oscillator, the SiT8503. This product is ideal for audio, microcontroller, and industrial applications. Boasting an extensive product portfolio in the silicon MEMS industry, SiTime offers megahertz (MHz) frequency, voltage-regulated oscillators, clock generators, VCXOs, spread spectrum timing products, and embedded resonators. By adding the SiT8503 kilohertz (kHz) frequency oscillator to its timing solution product portfolio, SiTime has established itself as a one-stop silicon timing provider.
“With silicon MEMS technology and programmable structural functions, the SiT8503 offers unique features not found in quartz oscillators: frequency and voltage configuration settings, a small package, low power consumption, and optimal robustness,” said Piyush Sevalia, Vice President of Marketing at SiTime. “SiTime, which is rapidly expanding its customer base, is replacing customers’ existing quartz oscillators with silicon MEMS solutions, and its extensive product portfolio, which leads the silicon timing solution industry, is serving as the foundation for SiTime to become a strategic supplier of timing components to major OEMs worldwide.”

Key Features and Advantages of SiT8503
• The ability to program frequencies within the range of 200kHz to 1000kHz (accuracy up to 5 decimal) can support various applications and optimize the frequencies of design applications.
• Support for a wide operating voltage range, including configurations such as 1.8V, 2.5V, 2.8V, or 3.3V, can reduce costs by eliminating expensive external level transformers and minimizing the need for additional regulators in the system.
• Provides superior ruggedness not found in quartz, offering up to 50,000 G impact resistance and up to 70 G vibration resistance.
• Frequency capability configurable to ±20 PPM, ±25 PPM, ±30 PPM, or ±50 PPM allows (customers) to optimize the optimal timing margin for their system.
• 100% drop-in replacement with 4 industry standard surface-mount packages (7.0x5.0 mm, 5.0x3.2 mm, 3.2x2.5 mm, and 2.5x2.0 mm)
• Guarantees extended battery life with power consumption of less than 10µA in standby mode.
SiT8503 samples are currently available, and mass production will be possible as of September 30, 2010. The SiT8503, with a 50 PPM tolerance and a 7.0 x 5.0 mm package, is 10
