Why do I need the external VCXO for the 8V19N407 / 8V19N408?

The VCXO component is the voltage controlled oscillator of the devices' first PLL stage. It is needed in all applications using the first stage for either jitter attenuation, frequency translation, or both. If only the second PLL stage is used (PLL BYPASS), the VCXO component is not needed.

For other questions not addressed by the knowledge base, please submit a technical support request.
