DSC1001
1.8~3.3V Low-Power Precision CMOS Oscillator
General Description
The 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 to 150MHz with supply voltages
between 1.8 to 3.3 Volts and temperature
ranges up to -40ºC to 105ºC.
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.
