Low-Jitter Precision LVDS Oscillator

DSC1103

DSC1123

General Description

The DSC1103 & DSC1123 series of high

performance oscillators utilizes a proven

silicon MEMS technology to provide excellent

jitter and stability over a wide range of

supply voltages and temperatures.

By

eliminating the need for quartz or SAW

technology, MEMS oscillators significantly

enhance reliability and accelerate product

development, while meeting stringent clock

performance

criteria

for

a

variety

of

communications, storage, and networking

applications.

DSC1103 has a standby feature allowing it to

completely power-down when EN pin is

pulled low; whereas for DSC1123, only the

outputs are disabled when EN is low. Both

oscillators are available in industry standard

and are “drop-in” replacements for standard

6-pin LVDS quartz crystal oscillators.
