DSC1030
3.0V
Low-Power CMOS Oscillator
General Description
The DSC1030 is a 3.0V fixed frequency
MEMS based PureSilicon™ Oscillator. It can
be factory programmed to any frequency
from 1 to 150MHz.
The DSC1030 incorporates an all silicon
resonator that is extremely robust and
nearly immune to stress related fractures,
common to crystal based oscillators.
Without sacrificing the performance and
stability required of today’s systems, a
crystal-less design allows for a higher level
of reliability, making the DSC1030 ideal for
rugged,
industrial,
and
portable
applications where stress, shock, and
vibration can damage quartz crystal based
systems.
Available in industry standard packages,
the DSC1030 can be “dropped-in” to the
same PCB footprint as standard crystal
oscillators.

Notes:
1.
Absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be
operated beyond these limits.
