DSA400屬于晶體振蕩器諧振器的振蕩器。由微芯科技股份有限公司制造生產的DSA400振蕩器振蕩器產品用作頻率/時間基準源，與常用于類似用途的晶體產品相比，區(qū)別在于它們集成了更多功能，用于生成輸出的保持和穩(wěn)定。最簡單的振蕩器包括晶體或其他諧振元件，并且具備必要的功能，讓用戶能夠獲取頻率基準，而無需密切關注諧振元件的工作。更先進的器件還集成了溫度補償或控制功能，以獲取更穩(wěn)定的基準或能夠進行選擇性調節(jié)的基準。

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.
