Recommendations for Unused Input and Output Pins
Inputs:
CLK/nCLK Inputs
For applications not requiring the use of the differential input, both
CLK and nCLK can be left floating. Though not required, but for
additional protection, a 1kΩ resistor can be tied from CLK to ground.
PCLK/nPCLK Inputs
For applications not requiring the use of the differential input, both
PCLK and nPCLK can be left floating. Though not required, but for
additional protection, a 1kΩ resistor can be tied from PCLK to
ground.
LVCMOS Control Pins
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.

Outputs:
LVPECL Outputs
All unused LVPECL outputs can be left floating. We recommend that
there is no trace attached. Both sides of the differential output pair
should either be left floating or terminated.
