General Description

The DSC400 is a four output crystal-less™ clock

generator. It utilizes proven PureSilicon™ MEMS

technology to provide excellent jitter and stability while

incorporating additional device functionality.

The nominal frequencies of the outputs can be identical

or independently derived from common PLLs.

Each output may be configured independently to

support a single-ended LVCMOS interface or a

differential interface. Differential options include

LVPECL, LVDS, or HCSL.

The DSC400 provides two independent select lines for

choosing between two sets of pre-configured

frequencies per bank. It also has two OE pins to allow

for enabling and disabling outputs.

The DSC400 is packaged in a 20-pin QFN (5 mm x

3.2 mm) and is available in extended commercial and

industrial temperature grades.
