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.
