Application Information

Recommendations for Unused Input and Output Pins

Inputs:

CLK/nCLK Inputs

For applications not requiring the use of the differential input, both

CLKx and nCLKx can be left floating. Though not required, but for

additional protection, a 1k

Ω resistor can be tied from CLKx 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:

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.

LVCMOS Outputs

All unused LVCMOS output can be left floating. There should be no

trace attached.
