DSC1018 Low-Power CMOS Oscillator 1.8V Features General Description The DSC1018 is a 1.8V fixed frequency MEMS based PureSiliconTM Oscillator. It can be factory programmed to any frequency from 1 to 150MHz. The DSC1018 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 DSC1018 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC1018 can be "dropped-in" to the same PCB footprint as standard crystal oscillators. Frequency Range: 1 to 150MHz Exceptional Stability over Temperature o 25 PPM, 50 PPM Operating voltage o 1.65 to 1.95V Operating Temperature Range o Industrial -40C to 85C o Ext.

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.
