Functional Description
The CY2X014/CY2X0147 device is a high-performance and
high-frequency XO. The device uses a Cypress proprietary
low-noise PLL to synthesize the frequency from an integrated
crystal.
The CY2X014/CY2X0147 device is available as a
factory-configured device or as a field-programmable device.
Factory-configured devices are configured for general use or
they can be customer-specific. The same CY2X014/CY2X0147
can be configured as four different device types as mentioned in
the Logic Block Diagram.
