87949AYI
For applications not requiring the use of a clock input, it can
be left floating. Though not required, but for additional
protection, a 1kΩ resistor can be tied from the CLK input to
ground.
PCLK/nPCLK I
For applications not requiring the use of a differential input,
both the PCLK and nPCLK pins can be left floating. Though
not required, but for additional protection, a 1kΩ resistor can
be tied from PCLK to ground.

CLK I
All control pins have internal pull-ups or pull-downs; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
