DSA400晶体振荡器谐振器的振荡器规格书PDF中文资料

DSA400属于晶体振荡器谐振器的振荡器。由微芯科技股份有限公司制造生产的DSA400振荡器振荡器产品用作频率/时间基准源，与常用于类似用途的晶体产品相比，区别在于它们集成了更多功能，用于生成输出的保持和稳定。最简单的振荡器包括晶体或其他谐振元件，并且具备必要的功能，让用户能够获取频率基准，而无需密切关注谐振元件的工作。更先进的器件还集成了温度补偿或控制功能，以获取更稳定的基准或能够进行选择性调节的基准。

General Description

The DSA400 is a four output clock generator. It utilizes proven PureSilicon™ MEMS technology to provide excellent jitter and stability while incorporating additional device functionality.

The nominal frequencies of the outputs can be identical or independently derived from common PLLs.

The four output DSA400 MEMS oscillators are excellent choices for use as clock references in automotive applications in which small size, low power consumption, and long-term reliability are paramount. The DSA400 is AEC-Q100 qualified.
