Xsis Electronics Inc. was founded in April 1978. At Xsis, we specialize in the design and manufacturing of High Reliability Crystal Units and Crystal Oscillators for Military, Space, Industrial, Telecommunication and extremely high temperature down hole applications.

Xsis is on the Qualified Products List for MIL-PRF-55310 (QPL) Military oscillators and MIL-PRF-3098 (QPL) Military crystal units.

 

Xsis is also a leading supplier of Rad-Hard Crystal Oscillators for Space Applications. Xsis has performed extensive Single Event Latch up (SEL) and Single Event Upset (SEU) testing on its Space Qualified Crystal Oscillators. Please visit our Space Products page for additional information on Space Products. 

Over 39 years of experience and expertise with quartz crystals and hybrid microcircuit technologies have earned Xsis the status of a certified supplier and a reputation among its customers as the most reliable supplier of advanced design microcircuit crystal oscillators. 

By using proven designs and quality components, continually monitoring work in process, testing every finished oscillator/crystal unit and using only hermetically sealed metal or ceramic packages can the user be assured of what our customers call “Experienced Reliability”.

Exceptionally good frequency aging characteristics are achieved by the use of precision quartz crystals manufactured using in-house proprietary processes.
