Abstract: A function-differentiated temperature compensated crystal oscillator (10) is disclosed having an integrated circuit, at least one capacitor and a piezoelectric element being electrically coupled to a leadframe, and being encapsulated in a molded package body (36). The leadframe includes two pluralities of leads (20, 26), each plurality accessing different functionalities of the temperature compensated crystal oscillator. In accordance with one embodiment of this invention, the first plurality of leads (20) may be excised preventing user access to internal functions of the oscillator. In accordance with another embodiment of this invention, the second plurality of leads (26) may be excised allowing user access to the internal functions of the oscillator. This configuration enables a single package to be used for different user applications and functions.

Abstract translation: 公开了一种功能分化温度补偿晶体振荡器（10），其具有集成电路，至少一个电容器和压电元件电耦合到引线框架，并被封装在模制封装主体（36）中。 引线框架包括两个多个引线（20,26），每个引线都访问温度补偿晶体振荡器的不同功能。 根据本发明的一个实施例，可以切除第一组多个引线（20），防止用户访问振荡器的内部功能。 根据本发明的另一个实施例，可以切除第二多个引线（26），以允许用户访问振荡器的内部功能。 此配置使单个包可以用于不同的用户应用程序和功能。
