Functional Description
The CY2XF24 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 using the I²C Bus serial interface,
allowing easy frequency margin testing in applications.
The CY2XF24 is available as a factory configured device or as
a field programmable device.
