CDCE6214-Q1EVM User's Guide

The CDCE6214-Q1EVM is an evaluation platform for the CDCE6214-Q1 automotive Q1-grade, ultra-low
power clock generator. This evaluation module uses a USB interface to supply power and program the
device. The quick start guide describes the basic configurations the designer can use to start the EVM,
and all the different modes of operations are described in subsequent sections.
