DSC1003

DSC1003 1.8~3.3V Low-Power Precision CMOS Oscillator General Description The DSC1003 is a silicon MEMS based CMOS oscillator offering excellent jitter and stability performance over a wide range of supply voltages and temperatures. The device operates from 1 to 150MHz with supply voltages between 1.8 to 3.3 Volts and extended temperatures from -40ºC to 105ºC. The DSC1003 has the same functionality and performance as the DSC1001 but with greater output drive (CL< 25pf). The DSC1003 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 DSC1003 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal based systems. Available in industry standard packages, the DSC1003 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.
