Low-Power Precision CMOS Oscillator
General Description
Features
Frequency Range: 1 to 150MHz
Exceptional Stability over Temperature
o ±10 PPM , ±25 PPM, ±50 PPM
Operating voltage
The DSC1004 is a silicon MEMS based CMOS
oscillator offering excellent jitter and stability
performance over a wide range of supply
o 1.7 to 3.6V
voltages and temperatures.
The device
Operating Temperature Range
o Ext. Industrial -40ºC to 105ºC
o Industrial -40ºC to 85ºC
o Ext. Commercial -20ºC to 70ºC
o Commercial 0ºC to 70ºC
Low Operating and Standby Current
o 8mA Operating (40MHz)
o 15uA Standby
Ultra Miniature Footprint
o 2.5 x 2.0 x 0.85 mm
o 3.2 x 2.5 x 0.85 mm
o 5.0 x 3.2 x 0.85 mm
o 7.0 x 5.0 x 0.85 mm
Excellent Shock and Vibration
Resistance
operates from 1 to 150MHz with supply voltages
between 1.8 to 3.3 Volts and extended
temperatures from -40ºC to 105ºC. The
DSC1004 has the same functionality and
performance as the DSC1001 but with greater
output drive (CL< 40pf).
The DSC1004 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 DSC1004
ideal for rugged, industrial, and portable
applications where stress, shock, and vibration
can damage quartz crystal based systems.
Lead Free, RoHS & Reach SVHC
Compliant
Available in industry standard packages, the
DSC1004 can be “dropped-in” to the same PCB
footprint as standard crystal oscillators.
Benefits
Pin for pin “drop in” replacement for
industry standard oscillators
Semiconductor level reliability,
significantly higher than quartz
Short mass production lead-times
Longer Battery Life / Reduced Power
Compact Plastic package
