DSC1025 2.5V Low-Power CMOS Oscillator General Description Features Frequency Range: 1 to 150MHz The DSC1025 is a 2.5V fixed frequency Exceptional Stability over Temperature MEMS based PureSilicon Oscillator. It can o 25 PPM, 50 PPM be factory programmed to any frequency Operating voltage from 1 to 150MHz. o 2.3 to 2.7V Operating Temperature Range The DSC1025 incorporates an all silicon o Industrial -40C to 85C resonator that is extremely robust and o Ext. Commercial -20C to 70C nearly immune to stress related fractures, o Commercial 0C to 70C common to crystal based oscillators. Low Operating and Standby Current Without sacrificing the performance and o 3mA Operating (40MHz) stability required of todays systems, a o 1uA Standby crystal-less design allows for a higher level Ultra Miniature Footprint of reliability, making the DSC1025 ideal for o 2.5 x 2.0 x 0.85 mm o 3.2 x 2.5 x 0.85 mm rugged, industrial, and portable o 5.0 x 3.2 x 0.85 mm applications where stress, shock, and o 7.0 x 5.0 x 0.85 mm vibration can damage quartz crystal based Excellent Shock and Vibration systems. Resistance Available in industry standard packages, Lead Free, RoHS & Reach SVHC Compliant the DSC1025 can be dropped-in to the same PCB footprint as standard crystal oscillators.
