9VRS4338D - Renesas

9VRS4338D VERY LOW POWER CLOCK

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 diffe.
