SUNNYVALE, Calif., 10 April 2008.Mobius Microsystems Inc. in Sunnyvale, Calif., is introducing a monolithic all-CMOS frequency generators based on CMOS Harmonic Oscillator (CHO) technology to displace quartz crystals and micro electro mechanical systems (MEMS)-based devices.
Electronics designers have long considered that an all-CMOS resonator would be the best possible solution for timing-reference needs, says Mobius Marketing Director Tunc Cenger.
Frequency generators are integral components of all electronics and systems that need to communicate data. "Frequency references and oscillators are essential components for a broad range of applications," says Steve Cullen, a contributing analyst at market researcher InStat in Scottsdale, Ariz. "Mobius' CMOS Harmonic Oscillator ... fits perfectly with the timing industry's continued drive toward more integrated and smaller package solutions," he says.
Mobius claims that its CHO technology is appropriate for today's common high-speed interface links. Mobius is targeting applications like USB devices.
Quartz and MEMS-based solutions require external components, yet Mobius's CHO technology allows mainstream electronics to "finally be rid of the last non-CMOS component ... and achieve the highest levels of integration." The technology is built on a standard CMOS process, and benefits from a well-established manufacturing infrastructure.
Mobius' first announced product to use CHO technology is the MM8511 integrated spread spectrum clock generator integrated circuit. The device replaces a quartz crystal and a PLL timing IC, and offers a one-chip solution to reduce electromagnetic interference.
