DSC1004
1.8~3.3V
Low-Power Precision CMOS Oscillator
General Description
The DSC1004 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 extended temperatures from -40ºC to
105ºC. The DSC1004 has the same
functionality and performance as the
DSC1001 but with greater output drive
(C
L
< 40pf).
The DSC1004 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 DSC1004 ideal for
rugged,
industrial,
and
portable
applications where stress, shock, and
vibration can damage quartz crystal based
systems.
Available in industry standard packages,
the DSC1004 can be “dropped-in” to the
same PCB footprint as standard crystal
oscillators.
