Device Overview

Summary

The DSC400 is a four output crystal-less™ clock generator. It utilizes Micrel’s proven PureSilicon™ MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The 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 preconfigured 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 (5mm x 3.2mm) and is available in extended commercial and industrial temperature grades.

Create an application specific part and order samples with the CLOCKWORKS CONFIGURATOR tool.
