DS125BR401A: DS125BR401A VDD input

Part Number: DS125BR401A

Hi,

I am using the DS125BR401A Linear Repeater in two places.  One is for a x4 PCIe.  The other is only a x2 but I want to use the same part to minimize the types of parts on the BOM.  To terminate the unused inputs, I was going to pull the “+” input to VDD with a 1K resistor.  The “-“ input in pulled to GND with a 1K.

I didn’t see anything in the data sheet about this.  Is this reasonable?  If not, how should they be terminated?

Thanks,

David
