• Manufacturer: PhaseLink Corp.

3. AC Electrical Specifications
4. Voltage Control Crystal Oscillator (3.3V)
Note: Parameters denoted with an asterisk (*) represent nominal characterization data and are not production tested to any specific limits.
5. Jitter and Phase Noise specification
6. Crystal Specifications
Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at
nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally.
This however may reduce the pull range.
