DSC1003

1.8~3.3V

Low-Power Precision CMOS Oscillator

MK-Q-B-P-D-083010-01-4

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

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.
