... AMD GEODE™ GX2 CLOCK SOURCE Description The MK1491- 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 ...

... Buffered reference output of 14.31818 MHz. Spread latched input upon power up. Spread is applied to all clocks except REFCLK’s and 48 MHz. Power must be cycled for a change of state to be detected. This pin has a weak internal pull-up resistor. See spread table. 3 CLOCK SYNTHESIZER Pin Description MK1491-09 REV L 121809 ...

... 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 ...
