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.
