General Description

The DSC400-4334Q0022 is a four output crystal-less? clock generator. It utilizes Microchips 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 two shared PLLs. Each output may be configured independently to support LVCMOS, LVPECL, LVDS, or HCSL output standards.

The DSC400-4334Q0022 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.
