Description
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.
