DSC8004
DSC8004 Series
1.8~3.3V Programmable Low-Power Precision CMOS Oscillator
General Description
The DSC8004 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 DSC8004 has the same functionality and
performance as the DSC8001 but with greater
output drive (CL=40pf).
The DSC8004 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 DSC8004
ideal for rugged, industrial, and portable
applications where stress, shock, and vibration
can damage quartz crystal based systems.
Available in industry standard packages, the
DSC8004 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. tSU is time to stable output frequency after VDD is applied. tSU and tEN (after EN is asserted) are identical values.
3. Measured over 50k clock cycles.
