Low Power Programmable Timing Control Hub for Intel Systems

The 9LRS4206 is a low power CK505-compliant clock specification. This clock synthesizer provides a single chip solution for Intel processors and Intel chipsets. The 9LRS4206 is driven with a 14.318MHz crystal.


  • Supports tight ppm accuracy clocks for Serial-ATA and PCIEX
  • Supports programmable spread percentage and frequency
  • Uses external 14.318MHz crystal, external crystal load caps are required for frequency tuning
  • Low power differential clock outputs (No 50 resistor to GND needed)
  • Integrated 33Ω series resistor on all differential outputs
  • Meets PCIEX Gen2 Specification
  • CPU outputs cycle-cycle jitter < 85ps
  • PCIEX outputs cycle-cycle jitter < 125ps
  • SATA outputs cycle-cycle jitter < 125ps
  • ±100ppm frequency accuracy on CPU, PCIEX and SATA clocks
  • ±100ppm frequency accuracy on USB clocks
