The Connor-Winfield Corporation is a privately held, US based electronic product manufacturer. After incorporation in 1963, Connor-Winfield focused primarily on designing and manufacturing quartz based timing circuits and oscillators for use in a wide variety of electronics applications. In the 1990's, Connor-Winfield expanded into other product areas while maintaining a continued focus on its core timing roots.

Connor-Winfield's frequency control products are used in a wide variety of applications including telecommunications, LAN and WAN products, computer, and other microprocessor and electronic equipment. We specialize in designing custom and semi-custom frequency control products but also offer a broad line of standard oscillator products and non-crystal based oscillators.

自1881年成立以来，精工推出了一款又一款革命性的产品，包括1913年日本首款腕表和1969年全球首款石英表。合并后的公司现在在广泛的领域开展业务，从手表到电子设备、半导体、眼镜、钟表和其他产品。这些个体企业中的每一个都致力于通过其业务联盟实现进一步的飞跃。

Since its founding in 1881, Seiko has introduced one revolutionary product after another, including the first wrist watch in Japan in 1913 and the first quartz watch in the world in 1969. The consolidated companies now operate in a broad range of fields, from watches to electronic devices, semiconductors, eyewear, clocks and other products. Each one of these individual businesses strives for further leaps forward through its business alliances.

泛音石英晶体的工作方式,Q 27.12-JXS21-9-10/15-T1-FU-WA-LF晶振，快速流畅的数据传输在当今世界至关重要。网络和服务器系统都旨在以闪电般的速度处理和转发信息。自此，许多应用开始依赖于三位数兆赫 （MHz）范围。

如此高的频率不能用基波音中的AT晶体产生。虽然基频为40至50MHz的石英盘是可行的，但它们的生产涉及相当大的努力和相应的成本。出于这个原因，“泛音晶体”通常用于20兆赫兹以上的频率。
