DSC1028 2.8V Low-Power CMOS Oscillator Features General Description Frequency Range: 1 to 150MHz Exceptional Stability over Temperature The DSC1028 is a 2.8V fixed frequency MEMS o 25 PPM, 50 PPM based PureSilicon Oscillator. It can be factory Operating voltage programmed to any frequency from 1 to o 2.6 to 3.0V 150MHz. Operating Temperature Range o Industrial -40C to 85C The DSC1028 incorporates an all silicon o Ext. Commercial -20C to 70C resonator that is extremely robust and nearly o Commercial 0C to 70C immune to stress related fractures, common to Low Operating and Standby Current crystal based oscillators. Without sacrificing the o 3mA Operating (40MHz) performance and stability required of todays o 1uA Standby systems, a crystal-less design allows for a Ultra Miniature Footprint higher level of reliability, making the DSC1028 o 2.5 x 2.0 x 0.85 mm ideal for rugged, industrial, and portable o 3.2 x 2.5 x 0.85 mm applications where stress, shock, and vibration o 5.0 x 3.2 x 0.85 mm can damage quartz crystal based systems. o 7.0 x 5.0 x 0.85 mm Excellent Shock and Vibration Available in industry standard packages, the Resistance DSC1028 can be dropped-in to the same PCB Lead Free, RoHS & Reach SVHC footprint as standard crystal oscillators.
