General Description
The DSC1001/3/4 is a silicon MEMS based CMOS
family of oscillators that offers excellent jitter and
stability performance over a wide range of supply
voltages and temperatures. The device operates from
1 MHz to 150 MHz with supply voltages between 1.8 to
3.3 volts and temperature ranges up to –40°C to
105°C.
The DSC1001/3/4 incorporate 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
DSC1001/3/4 ideal for rugged, industrial, and portable
applications where stress, shock, and vibration can
damage quartz crystal based systems.
Available in industry standard packages, the
DSC1001/3/4 can be “dropped-in” to the same PCB
footprint as standard crystal oscillators.
The DSC1003 and DSC1004 have the same
functionality and performance as the DSC1001, but
feature higher output drives of 25 pF and 40 pF,
respectively.
