DSC1033
3.3V
Low-Power CMOS Oscillator
MK-Q-B-P-D-031809-01-7
General Description
The DSC1033 is a 3.3V fixed frequency MEMS
based PureSilicon™ Oscillator. It can be factory
programmed to any frequency from 1 to
150MHz.
The DSC1033 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 DSC1033
ideal for rugged, industrial, and portable
applications where stress, shock, and vibration
can damage quartz crystal based systems.
Available in industry standard packages, the
DSC1033 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. See typical cycle to cycle jitter graph for frequency dependence.
