Crystal-less Two Output Clock Generator

DSC511-03

General Description

The DSC511-03 is a crystal-less, two output

clock generator. The clock generator uses

proven silicon MEMS technology to provide

excellent jitter and stability over a wide

range of supply voltages and temperatures.

By eliminating the external quartz crystal,

MEMS

clock

generators

significantly

enhance reliability and accelerate product

development, while meeting stringent clock

performance

criteria

for

a

variety

of

communications, storage, and networking

applications.

DSC511-03 has a Output Enable / Disable

feature allowing it to disable the outputs

when OE is low. The device is available in a

space saving 6 pin 2.5 x 2.0 mm QFN

package.
