DSC2010
Low-Jitter Configurable CMOS Oscillator
General Description
The DSC2010 series of high performance
CMOS oscillators utilize a proven silicon
MEMS technology to provide excellent jitter
and stability while incorporating additional
device functionality. The DSC2010 allows
the user to easily modify the frequency and
drive strength of the oscillator using pins.
The DSC2010 has provision for up to four
user-defined pre-programmed, pin-selectable
output frequencies, and eight pin-selectable
output drive levels to help reduce EMI.
DSC2010 is packaged in a 14-pin 3.2x2.5
mm QFN package and available in
temperature grades from Ext. Commercial to
Automotive.
