General Description

The DSC1103 and 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. For

DSC1123, only the outputs are disabled when EN is

low. Both oscillators are available in industry standard

packages, including the smallest 2.5 mm x 2.0 mm,

and are drop-in replacements for standard 6-pin LVDS

crystal oscillators.
