Functional Description
The CY2XF23 is a high-performance and high-frequency XO. It
uses a Cypress proprietary low-noise PLL to synthesize the
frequency from an integrated crystal. The output frequency can
be changed using the I²C bus serial interface, allowing easy
frequency margin testing in applications.
The CY2XF23 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.
