AMD GEODE™ GX2 CLOCK SOURCE
Description
The MK1491-09 is a low-cost, low-jitter, high-performance
clock synthesizer for AMD’s Geode-based computer and
portable appliance applications. Using patented analog
Phased-Locked Loop (PLL) techniques, the device accepts
a 14.318 MHz crystal input to produce multiple output
clocks. It provides selectable PCI local bus clocks, 48 MHz
clocks for Super I/O and USB, as well as multiple Reference
outputs.
The device has multiple power-down modes to reduce
power consumption.

... The MK1491-09 requires some inexpensive external components for proper operation. Decoupling capacitors of 0.1µF should be connected on each VDD pin to ground, as close to the MK1491-09 as possible. A series termination resistor of 33 may be used for each clock output. See the discussion below for other external resistors required for proper I/O operation ...
