Low-Jitter Configurable HCSL Oscillator

DSC2040

General Description

The DSC2040 series of high performance

dual output oscillators utilize a proven silicon

MEMS technology to provide excellent jitter

and stability while incorporating additional

device functionality.

The two outputs are

controlled by separate supply voltages to

allow

for

high

output

isolation.

The

frequencies of the outputs can be identical or

independently derived from a common PLL

frequency source.

The

DSC2040

has

provision for up to eight user-defined pre-

programmed,

pin-selectable

output

frequency combinations.

DSC2040 is packaged in a 14-pin 3.2x2.5

mm

QFN

package

and

available

in

temperature grades from Ext. Commercial to

Industrial.
