Low-Jitter Configurable Dual CMOS Oscillator

DSC2011

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.
