9VRS4339BKLFT

DATASHEET 9VRS4339B VERY LOW POWER CLOCK FOR 2011 NETBOOKS General Description Features/Benefits The 9VRS4339B 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. • Supports Wake_On_LAN (see pin55 pin description) • Selectable spread % on CPU, SRC, PCI; Supports Output Features • • 2 – 0.8V push-pull differential CPU pairs 5 – 0.8V push-pull differential SRC pairs 1 – 0.8V push-pull differential SATA pair 1 – 0.8V push-pull differential DOT96/SRC pair 1 – 0.8V push-pull differential LCD100 pair 1 – 0.8V push-pull differential CPU_ITP/SRC pair 2 – PCI (33MHz) 1 – PCI_F, (33MHz) free-running 1 – USB_48MHz 1 – 48MHz 1 – 25MHz 1 – 27MHz/PCI 1 – 14.318MHz • 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
