DSC1028

DSC1028 2.8V Low-Power CMOS Oscillator General Description The DSC1028 is a 2.8V fixed frequency MEMS based PureSilicon™ Oscillator. It can be factory programmed to any frequency from 1 to 150MHz. The DSC1028 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 DSC1028 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC1028 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.
