DSC1018
1.8V Low-Power CMOS Oscillator
General Description
Features
Frequency Range: 1 to 150MHz
The DSC1018 is a 1.8V fixed frequency
Exceptional Stability over Temperature
MEMS based PureSilicon Oscillator. It can
o 25 PPM, 50 PPM
be factory programmed to any frequency
Operating voltage
from 1 to 150MHz.
o 1.65 to 1.95V
Operating Temperature Range
The DSC1018 incorporates an all silicon
o Industrial -40C to 85C
resonator that is extremely robust and
o Ext. Commercial -20C to 70C
nearly immune to stress related fractures,
o Commercial 0C to 70C
common to crystal based oscillators.
Low Operating and Standby Current
Without sacrificing the performance and
o 3mA Operating (40MHz)
stability required of todays systems, a
o 1uA Standby
crystal-less design allows for a higher level
Ultra Miniature Footprint
of reliability, making the DSC1018 ideal for o 2.5 x 2.0 x 0.85 mm
o 3.2 x 2.5 x 0.85 mm
rugged, industrial, and portable
o 5.0 x 3.2 x 0.85 mm
applications where stress, shock, and
o 7.0 x 5.0 x 0.85 mm
vibration can damage quartz crystal based
Excellent Shock and Vibration
systems.
Resistance
Available in industry standard packages, Lead Free, RoHS & Reach SVHC
Compliant
the DSC1018 can be dropped-in to the
same PCB footprint as standard crystal
oscillators.
Benefits

Notes:
1. Absolute maximum ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be
operated beyond these limits.
2. t is time to stable output frequency after V is applied. t and t (after EN is asserted) are identical values.
