ILSI America was founded in 1987 with Headquarters in Costa Mesa, CA.  The business model at that time was simple, to become a supplier of Crystals and Clock Oscillators to support the North American Frequency Control Markets.

During the course of the next 29 years as World Wide market demand for Frequency Control Products grew exponentially and globalized, ILSI responded to meet the changing markets and customer base through organic growth and acquisition.

ILSI-MMD Inc. Sales Channel consists of 24 Territory Reps throughout the globe covering 45 of the 50 United States, Western and Eastern Canada, Mexico, Asia, United Kingdom, Poland, Germany, France, Italy, Austria, and South America.  The Sales Channel is also supported by a Distribution infrastructure consisting of a Multinational Tier 1 Distributor, Regional Distribution, USA based catalogue, and European based catalogue house; 8 total Franchised Distribution Channel Partners.

Today, ILSI-MMD Inc. is a Global Frequency Control Solutions provider.  Our goal is to supply the Global Frequency Control Marketplace with ISO9000:2008 Certified¸ very high quality, extremely competitively priced, and superior customer serviced Frequency Control Products.

In February 2017, ILSI America LLC acquired Ecliptek Corporation, a leading global manufacturer of crystal and oscillator products since 1987. The new company, Ecliptek LLC, will operate as a wholly owned subsidiary of ILSI, and will be headquartered in Reno, NV with an additional location in Southern California.
