DSC8001 Series
1.8~3.3V
Programmable Low-Power Precision CMOS Oscillator
General Description
The DSC8001 is a programmable 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 in increments of 100Hz (up to
four decimal point resolution) with supply
voltages between 1.8 to 3.3 Volts and
extended temperatures from -40ºC to
105ºC.
The DSC8001 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 DSC8001 ideal for
rugged,
industrial,
and
portable
applications where stress, shock, and
vibration can damage quartz crystal based
systems.
Available in industry standard packages,
the DSC8001 can be “dropped-in” to the
same PCB footprint as standard crystal
oscillators.
