Features

  • CPU outputs cycle-cycle jitter < 85ps
  • SRC output cycle-cycle jitter < 125ps
  • PCI outputs cycle-cycle jitter < 250ps
  • ± 100ppm frequency accuracy on CPU and SRC clocks
  • Does not require an external pass transistor for the voltage regulator
  • Integrated 33Ω series resistors on differential outputs, Zo = 50Ω
  • Supports spread spectrum modulation, default is 0.5% down spread
  • Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
  • Selectable between one SRC differential push-pull pair and two single-ended outputs
  • Meets PCIEX Gen2 specification on dedicated SRC outputs.
  • Muxed SRC outputs meet PCIEX Gen1 specification, except SRC1.
  • Single-ended programmable slew rate control for RFI reduction
  • Meets PCIEX <85ps cycle-to-cycle jitter for SRC[11:1]
  • Available in commercial and industrial temperature ranges
