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.
