Functional Description
The CY2XF34 is a high performance and high frequency Crystal
Oscillator (XO). It uses a Cypress proprietary low noise PLL to
synthesize the frequency from an integrated crystal. The output
frequency can be changed through two select pins, allowing
easy frequency margin testing in applications.
The CY2XF34 is available as a factory configured device or as
a field programmable device.
