p502-50dc PhaseLink Corp., p502-50dc Datasheet - Page 3

• Manufacturer Part Number: p502-50dc
• Description: Vcxo Ic Die For 20 To 52mhz Parallel Resonant Crystals
• Manufacturer: PhaseLink Corp.

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. 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.
6. Jitter specifications
7. Phase noise specifications
Note: Phase Noise at VCON = 0V
