Discera Expands MEMS Oscillator Product Line with Industrial Temperature Parts
(Nanowerk News) Discera, a recognized leader in MEMS oscillator technology, has expanded its PureSilicon product offering to include industrial temperature ranges with +/- 50ppm and +/- 25ppm frequency stability. Designers of computing, communication, portable and other electronic systems -- for both consumer and industrial applications -- now have access to the significant cost and power advantages offered by MEMS oscillator technology.
Discera’s PureSilicon MEMS oscillators are pin-compatible with popular crystal oscillators and have low operating current specs (3mA typ. at 40MHz), while consuming just 1uA in standby mode. Discera oscillators are also practically impervious to shock, vibration and fractures that can affect crystal parts. The combination of high reliability and very low power consumption make MEMS oscillators ideal for portable and battery operated applications. And with MEMS oscillators now costing 20% less than comparable crystal oscillators, they are also far more cost-effective for almost any application.
"2008 was long anticipated as the crossover year when MEMS oscillators would overtake crystal oscillators on a cost basis. Using industry standard CMOS processing techniques and plastic packaging, MEMS enjoy several important cost advantages over conventional crystal oscillators. As process geometries scale, these cost advantages will only grew more pronounced over time," said Rich Miller, Discera’s Vice President of Marketing. "With the addition of industrial temp ranges to Discera’s product line, all system manufacturers can now enjoy the cost, power, reliability and lead time benefits of MEMS oscillators."
According to a leading research firm, the market for MEMS oscillators is expected to grow at more 100% per annum through 2013 as this new technology rapidly expands its share of the $3 billion global frequency control market.
Pricing and Availability
Discera’s PureSilicon product line includes oscillators that support frequencies from 1 to 150 MHz; supply voltages of 1.8v, 2.5v, 2.8v, 3.0v and 3.3v; and industrial -40° to +85° C. temperature ranges, in addition to -20° to +70° C. extended commercial and 0° to +70° C. standard commercial temperature ranges.
PureSilicon industrial temperature range oscillator samples are currently available with production volumes available in 3Q of this year. PureSilicon oscillators are available in 2.5x2.0mm, 3.2x2.5mm, 5.0x3.2mm and 7.0x5.0mm plastic packages. With +/-25ppm frequency stability over the industrial temperature range, the 1.8v, DSC1018 device in a 5.0 x 3.2mm package is priced at $1.10 /ea. in 1,000 piece quantities.
Founded in 2001 as an extension of pioneering MEMS development work at UC Berkeley and U. of Michigan at Ann Arbor, Discera is a recognized leader in MEMS oscillator technology. The company has 27 MEMS technology patents. Discera was presented with the prestigious Wall Street Journal Innovation Award, and the company’s CTO has garnered the coveted ACE Award for his work on MEMS technology.
