... 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 and AC97 audio clocks, 24 MHz and 48 MHz clocks for Super I/O and USB, as well as multiple Reference outputs ...

... The MK1491-06 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 MK1491-06 as possible. A series termination resistor of 33Ω may be used for each clock output. See the discussion below for other external resistors required for proper I/O operation. The 14 ...
