SiTime has introduced the SiT8920 MEMS oscillator for industrial and high reliability applications. SiT8920 is claimed to perform better than quartz oscillators. SiT8920 withstands operating temperature range of -55°C to +125°C and consume half the power of quartz oscillators, is twice as stable, 20 times more reliable and 30 times more robust to shock and vibration, according to SiTime.
“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. SiTime’s MEMS oscillators incorporate unique features that are simply not available from quartz products. For example, the SiT8920 incorporates SiTime’s unique SoftEdge rise/fall time control that reduces system EMI without additional components, expensive shielding or PCB re-design. By offering such compelling benefits, SiTime is transforming the timing industry with its silicon MEMS solutions.”
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
The unique features and benefits of this oscillator family as per SiTime are listed below.
Best robustness: 30 times better than quartz oscillators
0.1 ppb/g vibration sensitivity, the best in the industry
50,000 g shock and 70 g vibration resistance
Best reliability: 500 million hours MTBF (2 FIT), 20 times better than quartz oscillators
Best frequency stability: ±25 PPM over the operating temperature for better system timing
Low power consumption:
