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 1k

Ω

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 1k

Ω resistor can be used.

Outputs:

LVDS Outputs

All unused LVDS output pairs can be either left floating or

terminated with 100

Ω across. If they are left floating, there should

be no trace attached.
