DSC1033AI2-008.0000T

Low-Power CMOS Oscillator

Micrel 

DSC1033

3.3V

Low-Power CMOS Oscillator

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.
