Taiwan's Jiashuo is the original parts division of Motorola. The crystal oscillators and filters produced by Jiashuo retain Motorola's technology, but have the same price as Taiwanese products, and are very cost-effective. The application range is very wide, including military industry and aerospace grade. And the products are relatively complete, including surface acoustic wave filters, radio frequency filters, temperature compensated crystal oscillators, voltage controlled crystal oscillators, constant temperature crystal oscillators, etc.
