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.
