DSC2030

Low-Jitter Configurable LVDS Oscillator

General Description

The DSC2030 series of high performance

LVDS oscillators utilize a proven silicon MEMS

technology to provide excellent jitter and

stability while incorporating additional device

functionality. The DSC2030 allows the user

to easily modify the frequency of the

oscillator using pins. The DSC2030 has

provision for up to four user-defined pre-

programmed,

pin-selectable

output

frequencies.

DSC2030 is packaged in a 14-pin 3.2x2.5

mm QFN package and available in

temperature grades from Ext. Commercial to

Automotive.
