The 9FGP202 is a peripheral clock for Intel Server. It is driven with a 25MHz crystal and generates CPU outputs up to 400MHz. An SMBus interface allows full control of the device.


  • 1 - 0.7V current-mode differential CPU pair
  • 8 - 50MHz output
  • 1 - DOT 96MHz output
  • 1 - 33.33MHz output
  • 1 - 32.768KHz output
  • 2 - 25MHz REF outputs
  • Selectable SMBus Address - D0/D1 or C0/C1
  • Spread Spectrum capability on CPU and DOT 96MHz clocks
  • SMBus Control: - M/N and spread programming on CPU and DOT 96MHz clocks via SMBus - Outputs can be disabled via pins or SMBus
  • Exact synthesis on CPU, RMII and 33.33MHz clocks
  • +/- 100ppm frequency accuracy on remaining clocks
