Application Information
Recommendations for Unused Input and Output Pins
Inputs:
CLK Inputs
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.
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.
3.3V LVDS Driver Termination
A general LVDS interface is shown in Figure 2. In a 100Ω
differential transmission line environment, LVDS drivers require a
matched load termination of 100Ω across near the receiver input.

Outputs:
LVDS Outputs
All unused LVDS output pairs can be either left floating or
terminated with 100Ω across. If they are left floating, there should
be no trace attached.
For a multiple LVDS outputs buffer, if only partial outputs are used,
it is recommended to terminate the unused outputs.
