Microchip Technology DSC400 Low Jitter Crystal-Less Clock Generator

Microchip Technology DSC400 Low Jitter Crystal-Less Clock Generator utilizes 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. This device also has two OE pins to allow for enabling and disabling outputs.

The Microchip Technology DSC400 is packaged in a 20-pin Quad Flat No-Lead (QFN) package and is available in extended commercial and industrial temperature grades.
