Additional Details:

The CDC319 operates from a single power supply voltage. The precise voltage range can vary between versions and should be verified against the device's datasheet. Configuration is often achieved through external resistors and capacitors to set the desired output frequencies. The device is often available in small form factor packages such as QFN to minimize board space. Specific performance metrics such as cycle-to-cycle jitter, period jitter, and long-term jitter are generally outlined in the datasheet for different operating conditions. Detailed information regarding power supply filtering and termination requirements should be referenced in the device's application notes.
