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 be glitched, and the PLL may require an additional tLOCK time before all datasheet limits are
achieved.
