DSC1001 CMOS Oscillators

Microchip's DSC1001 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 MHz to 150 MHz with supply voltages between 1.8 V to 3.3 V and temperature ranges up to -40°C to +105°C.

The DSC1001 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 DSC1001 ideal for rugged, industrial, and portable applications where stress, shock, and vibration can damage quartz crystal-based systems. Available in industry standard packages, the DSC1001 can be “dropped-in” to the same PCB footprint as standard crystal oscillators.
