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.
Each output may be configured independently to
support a single-ended LVCMOS interface or a
differential interface. Differential options include
LVPECL, LVDS, or HCSL.
The DSA400 provides two independent select lines for
choosing between two sets of pre-configured
frequencies per bank. It also has two OE pins to allow
for enabling and disabling outputs.
The DSA400 is packaged in a 20-pin QFN (5 mm x
3.2 mm) and is available in extended commercial and
industrial temperature grades.
The DSA400 is a highly configurable device and is
factory programmed to meet the customer’s needs.
