Functional Description
The CY2XF24 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.
