Note:

1. These inputs are normally wired to VCC , GND, or unconnected. Internal termination resistors bias unconnected inputs

to VCC/2. If these inputs are switched, the function and timing of the outputs may glitched, and the PLL may require

an additional tLOCK time before all datasheet limits are achieved.
