SiTime Adds +125C MEMS Oscillators High Reliability

SiTime introduced a MEMS oscillator offering a wide temperature range of-55°C to +125°C for industrial and high reliability applications.

Due to its unique silicon MEMS and analog architecture, the new SiT8920 outperforms quartz oscillators in every major performance category. It consumes half the power of quartz oscillators, is twice as stable, 20 times more reliable and 30 times more robust to shock and vibration.

SiTime also noted that its MEMS oscillators incorporate unique features that are  not available from quartz products, such as a unique "SoftEdgeT" rise/fall time control that reduces system EMI without additional components, expensive shielding or PCB re-design.

SiTime is also introducing two additional devices that are well suited for replacing quartz oscillators and crystal resonators.

SiT1618 – a fixed-frequency oscillator that operates over -40°C to +125°C

SiT8918 – a programmable oscillator that operates over the same temperature range and supports any frequency between 1 and 110 MHz as well as 1.8V and 2.5 to 3.3V operation

All three of the new MEMS oscillators are sampling now with mass production scheduled for April 2013.

"SiTime’s MEMS and analog expertise allows us to deliver unique, leadership products with performance that is far beyond what is available in the market today,” said Piyush Sevalia, executive vice president of marketing at SiTime. “The SiT8920 is a win-win for customers developing industrial and high-reliability applications. They benefit from dramatically better robustness and reliability, while simultaneously improving system performance.
