The 84325 is a Crystal-to-3.3 VLVPECL Frequency Synthesizer with Fanout Buffer. The output frequency can be programmed using frequency select pins. The low phase noise characteristics of the 84325 make it an ideal clocksource for Fibre Channel 1, Fibre Channel 2, Infiniband and Gigabit Ethernet applications.


  • 6 differential 3.3V LVPECL outputs
  • Crystal oscillator interface
  • Output frequency range: 106.25MHz to 250MHz
  • Crystal input frequency: 25MHz and 25.5MHz
  • Output skew: 60ps (maximum)
  • RMS phase jitter at 212.5MHz, using a 25.5MHz crystal (637KHz to 10MHz): 2.76ps
  • Phase noise: Typical at 212.5MHz
