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

Crystal MEMS
MEMS oscillators drop into standard oscillator footprints and offer advantages in performance, reliability, pricing, and time-to-market
Performance Advantage
Discera Confidential 6
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

Reliability Advantage
Discera Confidential 7
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

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
