... 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 K 072406 ...

... 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 ...
