Supporting the evolution from mechanically

ground and polished crystals…

…to consistent and reliable

semiconductor technology

What is MEMS?

MEMS Printer Heads

MEMS DLP Projectors MEMS Accelerometer

MEMS Microphone

MEMS stands for Micro-Electro-Mechanical Systems

– MEMS technology is proven, the first devices were produced in 1967

– It is widely used today to replace expensive, legacy technologies with higher performing, more capable semiconductor-based equivalents


MEMS Timing

Oscillators used in computing, networking, video and other applications where performance, reliability, size, and development time are important to deliver

Using Oscillators Instead of Plain Crystal

Higher and more stable performance

• Consistent timing independent of layout • Self contained device matches resonator

and drive circuitry • Less coupling of noise into circuitry

Faster time to market

• Tolerant of layout and PCB changes • Guaranteed timing accuracy

Higher reliability

• Minimal effect from board aging • Single component replaces crystal and load

capacitor • Insensitive to EMI, vibration and humidity

Better size and flexibility

• Smaller overall board space consumed by timing function

• Flexible PCB sourcing since PCB parasitics do not affect frequency control


Using MEMS Instead of Crystal Oscillators


Better performance stability

• Up to 10ppm stability across full temperature range

• Temperature grades up to 125C (vs 85C) • Less than 0.5 ps phase noise jitter


• 2 weeks production lead time vs. 8-16 weeks for crystal

• Engineering prototypes programmable in 1 sec with full production performance

Higher reliability

• Full JEDEC, MIL-STD qualification • 1.5 FIT reliability rates vs. 20 FIT for crystal • 50 000 G shock and 50 G vibration tolerance

(vs 200 G shock, 10 G vibration)

Better pricing

• Semiconductor supply chain, without mechanical handling steps of crystal

• On CMOS pricing trend, scaling with chip geometry in Global, TSMC processes

Crystal MEMS

MEMS oscillators drop into standard oscillator footprints and offer advantages in performance, reliability, pricing, and time-to-market

Performance Advantage


For a top networking manufacturer, performance was the reason to choose Discera. Discera ships the world’s highest performance MEMS

oscillators, delivering system-level performance that beats the 10 Gigabit Ethernet and 6G SAS specifications by 45-60%

Integrated Phase Noise 200KHz-20 MHz

0.3 ps

Reliability Advantage


For one of the world’s largest printer manufacturers, reliability was the reason to choose Discera. Discera MEMS offers 20x the MTBF of

crystal oscillators because they use semiconductor technology instead of fragile and contaminant-prone quartz crystal

Operating Advantage


For a major ODM, operating stability was the reason to choose Discera. Demand for smaller, fanless products resulted in system

failures when their internal temperature exceeded crystal oscillator design limits of 85C, while Discera MEMS is available in

105C and 125C grades with shock resistance of up to 50 000G
