DSC2011
Low-Jitter Configurable Dual CMOS Oscillator
General Description
The DSC2011 series of high performance
dual output CMOS oscillators utilize a proven
silicon MEMS technology to provide excellent
jitter and stability while incorporating
additional device functionality. The two
CMOS outputs are controlled by separate
supply voltages to allow for independent
voltage level control. The frequencies of the
outputs can be identical or independently
derived from a common PLL frequency
source. The DSC2011 has provision for up to
eight user-defined pre-programmed, pin-
selectable output frequency combinations.
The DSC2011 is also equipped with
independent pin-selectable output drive
strengths for each output to reduce EMI and
noise.
DSC2011 is packaged in a 14-pin 3.2x2.5
mm QFN package and available in
temperature grades from Ext. Commercial to
Automotive.
