Introduction

High Temperature Frequency Control SolutionsHigh Temperature electronics is a rapidly evolving technology with applications in engine control, energy exploration and industrial process control. In addition to the challenges related to the design and construction of silicon-based microelectronics above 150°C, quartz crystal oscillators introduce a unique set of design complexities. Traditional quartz oscillators exhibit significant frequency vs. temperature dependence above 125°C, and stresses due to CTE mismatches create additional frequency perturbations. In addition to elevated temperatures, many of these application subject the oscillator to extreme shock and vibration. Microchip’s staff of design and process engineers have developed proprietary solutions to address these challenges, starting at the processing of the raw quartz, through the electronic design, to the packaging and intercon-nect technologies required for the entire assembly.

Our StrengthsVectron brand high temperature products are manufactured in our AS9100 facility in Mount Holly Spring, Pennsylvania. The state-of-the-art hybrid manufacturing facility features oscillator and crystal manufacturing, two class 100,000 clean rooms, and an environmental laboratory.

Mechanical and electrical engineers with years of experience in high temperature electronic design collaborate with recent college graduates who infuse the latest technologies. Our oscillators, which are qualified to operate as high as 250°C, provide our customers with extended reliability without the need for expensive heat sinking solutions in light-weight, small form factor footprints.

Other Microchip facilities design and manufacture product that supplement our product offerings, including atomic clocks and SAW filters.

Export compliance officers at Microchip ensure full regulatory compliance on all products, whether, ITAR, CCL or EAR99.


Design

Design and Manufacturing TechnologiesThe design and manufacture of high temperature oscillators requires the use of specialized technologies from multiple technologi-cal disciplines. The list below summarizes these key technologies and capabilities:
