FOXcrystal美國福克斯晶振公司成立于1979年，是一家小型的家族企業(yè)。總部位于邁爾斯堡佛羅里達州。自福克斯晶振公司成立以來，便發(fā)展成為美國高精度，高可靠性頻率控制產(chǎn)品領(lǐng)先供應商，全球擁有10000多家客戶。過去的32年以來，研發(fā)部門是公司的持續(xù)增長的重要推動力。福克斯晶振工程師已經(jīng)開發(fā)出數(shù)百種產(chǎn)品，為晶體和振蕩器的精度及高可靠性設(shè)定了新的標準，并為了縮短交周期以滿足不同客戶的需求。
FOX晶振公司憑借先進的生產(chǎn)設(shè)備，及無塵工作室使得
福克斯晶振公司能夠生產(chǎn)出符合要求的產(chǎn)品。2012年4月美國IDT晶振公司成功收購福克斯晶振公司，并于2016年10月恢復福克斯晶振公司為長期管理團隊的權(quán)限。
Fox Electronics was founded in 1979 as a small, family-owned supplier of quartz crystals and oscillators. Since then, the company has evolved to become America’s leading supplier of high-precision, high-reliability frequency control products to the electronics market, with more than 10,000 customers worldwide.
An important contributor to the company's continuing growth over the last 32 years is its R&D department. Fox engineers have developed hundreds of products that have set new standards for crystal and oscillator performance, precision and reliability, as well as for meeting escalating business demands for shorter lead times.
Fox prides itself on being on the leading edge of frequency control technology with continued new product developments based on top quality company research.
With advanced manufacturing facilities incorporating state-of-the-art equipment operating under atmospherically controlled conditions – including a Class-100 clean room – Fox Electronics is able to produce its innovative products to the most stringent industry quality standards.
In April 2012 Integrated Device Technology, Inc. acquired Fox Electronics, and in October 2016 it returned to private ownership by Fox's long term management team.
