Overview

VERY LOW POWER CLOCK FOR 2011 NETBOOKS DATASHEET 9VRS4338D General Description The 9VRS4338D is a main clock for Intel Netbooks, conforming to the CK-NET specification.
It is driven with a 14.
31818MHz crystal and generates a variety of clocks, including an LCD clock.
An SMBus interface allows full control of the device.
Recommended Application CK-NET Output Features • 2 - 0.
8V push-pull differential CPU pairs • 3 - 0.
8V push-pull differential SRC pairs • 1 - 0.
8V push-pull differential SATA/SRC 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 • 3 - PCI (33MHz), 1 free-running • 1 - 25MHz _PCI (33MHz) • 1 - USB_48MHz • 1 - REF, 14.
318MHz Pin Configuration Features/Benefits • 25M output can run in power down; Supports Wake_On_LAN • Selectable spread % on CPU, SRC, PCI; Supports margining • External 14.
318MHz crystal; Supports tight ppm • CLKREQ# pins; Support SRC power management • Low power differential clock outputs; reduced power and board space • Integrated 33 ohm series resistors on all differential outputs; reduced board space Key Specifications • CPU cycle-to-cycle jitter <85ps • SRC/SATA cycle-to-cycle jitter <85ps • SRC(1:4) are PCIe Gen2 compliant • SRC5 is PCIe Gen1 compliant • ±100ppm frequency accuracy on all clocks except 25M • ±30ppm frequency accuracy on 25M GNDREF CLK PW RGD/PD# _3.
