DSC1001
1.8~3.3V
Low-Power Precision CMOS Oscillator
General Description
The DSC1001 is a silicon MEMS based
CMOS oscillator offering excellent jitter and
stability performance over a wide range of
supply voltages and temperatures.
The
device operates from 1 to 150MHz with
supply voltages between 1.8 to 3.3 Volts
and temperature ranges up to -40ºC to
105ºC.
The DSC1001 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 DSC1001 ideal for
rugged,
industrial,
and
portable
applications where stress, shock, and
vibration can damage quartz crystal based
systems.
Available in industry standard packages,
the DSC1001 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.
2.
t
SU
is time to stable output frequency after V

is applied. t
SU
and t
EN
(after EN is asserted) are identical values.
3.
Measured over 50k clock cycles.
