DSC1033 Low-Power CMOS Oscillator 3.3V Features General Description The DSC1033 is a 3.3V fixed frequency MEMS based PureSiliconTM 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. Frequency Range: 1 to 150MHz Exceptional Stability over Temperature o 25 PPM, 50 PPM Operating voltage o 3.0 to 3.6V Operating Temperature Range o Industrial -40C to 85C o Ext. Commercial -20C to 70C o Commercial 0C to 70C Low Operating and Standby Current o 3mA Operating (40MHz) o 1uA Standby Ultra Miniature Footprint o 2.5 x 2.0 x 0.85 mm o 3.2 x 2.5 x 0.85 mm o 5.0 x 3.2 x 0.85 mm o 7.0 x 5.0 x 0.85 mm Excellent Shock and Vibration Resistance Lead Free, RoHS & Reach SVHC Compliant Benefits Block Diagram VDD Resonator Output VCO PFD Applications Frac-N PLL Standby# (pin1) Pin for pin "drop in" replacement for industry standard oscillators Semiconductor level reliability, significantly higher than quartz Longer Battery Life / Reduced Power Compact Plastic package Cost Effective GND Mobile Applications Consumer Electronics Portable Electronics CCD Clock for VTR Cameras Low Profile Applications Industrial All Rights Reserved.
