Transcript of Applications About Mobius Microsystems - CSE · About Mobius Microsystems Based in Silicon Valley,...
About Mobius MicrosystemsBased in Silicon Valley, Mobius Microsystems is a fabless
semiconductor company, and the first to implement accurate
frequency generators on a single, standard CMOS die. This is a
significant technical breakthrough in frequency generation, which
up to now had been accomplished with quartz-based crystals,
crystal oscillators and PLL ICs. Mobius’ patented CMOS Harmonic
Oscillator (CHO™) eliminates such components, and enables
designers to create robust products offering higher frequency and
thinner profiles. Mobius’ proprietary technology builds on work
done at the University of Michigan by Michael McCorquodale,
Ph.D., CTO of the company. Mobius is funded by leading venture
capital firms, has an extensive patent portfolio, and has been
recognized as a company to watch by its industry peers.
“The industry has long recognized the value of building frequency
references monolithically in CMOS, but many thought it simply
could not be done, and that quartz crystals would always be
needed. Mobius proves the contrary; it can be done with CMOS.
Our technology enables smaller, thinner, and more mechanically
robust products for a wide array of applications.”

Mobius’ CHO is a simple, robust and reliable frequency reference for consumer, storage and computation applications. CHO replaces crystals, crystal oscillators and PLL ICs to simplify system design, reduce start-up latency and failure rates. The devices are built in reliable, standard CMOS process, and assembled in low profile plastic packages to support thin designs. The single-die CMOS oscillator eliminates the need for external oscillator circuits, precision load capacitors and protective pads. The low jitter, low phase noise CHO architecture doesn’t rely on any mechanical resonators and generates a broad range of programmable frequencies from kHz to 100s of MHz.

Mobius’ CMOS Harmonic Oscillator (CHO™) Mobius Microsystems develops accurate frequency references on monolithic CMOS ICs. The company allows the electronics industry to finally move beyond quartz-based crystals, or other mechanical resonators, to explore the many benefits of integration made possible only with an all-CMOS solution. The company’s patented CHO technology removes the high frequency limitation of fundamental mode crystals, and accommodates the thinnest IC packaging available today. This integrated and space-saving design eliminates the common frequency drift problems of crystal load capacitors, and offers excellent shock and vibration immunity. CHO products are package programmable, and shorten the manufacturing cycle time of frequency references significantly.
Thinner and Higher Frequency Products With a product height of 0.55mm for the Chip-Scale (uCSP) package option, the devices using CHO technology conform to the most stringent form factor requirements of next generation USB flash drives and other thin-profile consumer electronics products. The CHO can generate a broad range of high frequencies which can be programmed at the package level electrically. The monolithic CMOS approach enables complete integration of the frequency generation function and makes the CHO an ideal solution for Multi-Chip Module (MCM) or System-in-Package (SiP) devices.
High Accuracy CMOS OscillatorMobius’ CHO is the first all-CMOS oscillator to achieve very low frequency drift over temperature, voltage and process variations. The technology is proven to meet the requirements of common interface standards such as USB HS and S-ATA Gen 1 & 2.
Excellent Phase NoiseThe foundation of our patented design is a high frequency, high precision, harmonic (LC) resonator circuit with excellent phase noise and jitter performance. At higher offset frequencies, which are the most critical for low jitter performance, the CHO can achieve up to 20dB lower phase noise than common PLLs.
Mobius Microsystems’ technical achievements include:
• First commercial replacement of quartz crystals in a USB FS interface.
• First all-CMOS oscillator to match the accuracy, phase noise and jitter performance of quartz-based crystal oscillators
• An all-CMOS, integrated microprocessor clock with the fastest start-up time
• The first, fully integrated Spread Spectrum Clock Generator that eliminates the need for both quartz crystals and PLL ICs.
CHO Features:
• No external crystal or PLL ICs required
• Excellent phase noise and jitter
• Low power dissipation
• Best-in-class reliability
• Vibration and shock resistant
• Total accuracy: <+500ppm (USB), <+350ppm (SATA)
• Operating temperature: 0 to 70ºC
• 3.3V operation
The integration offered by Mobius Microsystems’ CHO technology enables thinner profile, higher frequency and more cost-effective consumer, storage and computation products. The company applies its patented technology to develop different classes of frequency references including:
• Singlefrequency,ultra-thinprofilereplacementsofbulkyquartzcrystals • Morereliable,higherfrequencyalternativestoexpensivecrystaloscillators • Programmable,single-chipsolutionstoreplacemultiplequartzcrystalsandoscillators • FullyintegratedtimingICsthateliminateboththecrystalandthePLLICs
The first product from Mobius Microsystems is a Spread Spectrum Clock Generator that doesn’t require any crystal references or PLL ICs. The programmable product demonstrates the benefits of integration and space savings offered by Mobius’ all-CMOS implementation of the frequency reference.
