Functional Description
The CY2X014 is a high-performance and high-frequency XO.
The device uses a Cypress proprietary low-noise PLL to
synthesize the frequency from an embedded crystal.
The CY2X014 is available as a factory-configured device or as
a field-programmable device. Factory-configured devices are
configured for general use (see Standard and
Application-Specific Factory Configurations) or they can be
customer specific.
