Our primary business is development and supply of frequency control products. Most of these frequency control products are quartz crystal based and include clock oscillators, VCXO, TCXO, TCVCXO and OCXO products, as well as quartz crystals in a variety of package types. We offer both surface mounted and leaded devices, including crystals and oscillators with tight tolerances and miniature packages, and crystal filters. Other frequency control products that are not based on quartz crystals include ceramic resonators and filters. Our Asian factories operate under ILSI's Factory Control Systems and are ISO 9001 certified. We are a recommended supplier for Chip Sets manufactured by Conexant, Alcatel, ST Micro, Motorola, and Hitachi and our frequency control products are very competitively priced.
