RECOMMENDATIONS FOR UNUSED INPUT

AND OUTPUT PINS

2.1.1

INPUTS

Control Pins

All control pins have internal pull-ups or pull-downs; additional resis-

resistor can be used.

Single-Ended Clock Inputs

For protection, unused single-ended clock inputs should be tied to

ground.

Differential Clock Inputs

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

*_POS and *_NEG can be left floating. Though not required, but for

2.1.2

OUTPUTS

Status Pins

For applications not requiring the use of a status pin, we recommend

bringing out to a test point for debugging purposes.

Single-Ended Clock Outputs

All unused single-ended clock outputs can be left floating, or can be

brought out to a test point for debugging purposes.

Differential Clock Outputs

All unused differential 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.
