Very Low Power Clock for Intel Netbooks

The 9VRS4339 is a Intel CK-NET compatible main clock for Intel Netbooks, conforming to the CK-NET specification. It is driven with a 25MHz crystal and generates a variety of clocks, including an LCD clock. An SMBus interface allows full control of the device.

Features

  • Supports Wake_On_LAN (see pin55 pin description)
  • Selectable spread % on CPU, SRC, PCI; Supports margining
  • Uses external 25MHz crystal, external crystal load caps are required for frequency tuning
  • CLKREQ# pins; Support SRC power management
  • Low power differential clock outputs driving 100 ohm differential traces; reduced powe
  • Integrated 33 ohm series resistors on all differential outputs; reduced board space
  • CPU outputs cycle-to-cycle jitter <85ps
  • SRC cycle-to-cycle jitter <85ps
  • SRC meets PCIEX Gen2 specifications
  • SATA outputs cycle-to-cycle jitter <125ps
  • PCI outputs cycle-to-cycle jitter <500ps
  • ±100ppm frequency accuracy on all clocks
