  • Supports spread spectrum modulation, default is 0.5% down spread
  • Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
  • Does not require external pass transistor for voltage regulator
  • Integrated 33Ω series resistors on differential outputs, Zo=50ΩCPU outputs cycle-cycle jitter < 85ps
  • SRC output cycle-cycle jitter < 125ps
  • +/- 100ppm frequency accuracy on all outputs
  • SRC are PCIe Gen2 compliant
