Recommendations for Unused Input and Output Pins
Inputs:
IN Inputs
For applications not requiring the use of a clock input, it can be left
floating. Though not required, but for additional protection, a 1k
resistor can be tied from the IN input to ground.
LVCMOS Control Pins
All control pins have internal pullups; additional resistance is not
required but can be added for additional protection. A 1k
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.
