DSC8002 Series
1.8 to 3.3V
Programmable Low-Power CMOS Oscillator
General Description
The DSC8002 is a programmable MEMS
based PureSilicon™ Oscillator. Using the
DragonFly™ or TimeFlash™ handheld
programmer, the end user can program the
DSC8002 within seconds to any frequency
from 1 to 150MHz in increments of 100Hz
(up to four decimal point resolution). The
nominal operational range spans from 1.8
to 3.3 Volts, without any need for
additional external components, providing
ease of use and flexibility in multi-voltage
applications.
The DSC8002 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 DSC8002 ideal for
rugged,
industrial,
and
portable
applications where stress, shock, and
vibration can damage quartz crystal based
systems.
Available in industry standard packages,
the DSC8002 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.
Output frequency to within 100ppm of final stable output frequency.
3.
See typical cycle to cycle jitter graph for frequency dependence.
