NOTE: (1) These inputs are normally wired to VDD, GND, or unconnected. Internal termination resistors bias unconnected
inputs to VDD/2. If these inputs are switched, the function and timing of the outputs may be glitched, and the PLL
may require an additional tLOCK time before all datasheet limits are achieved.
