Hello, I am working with the Utility Buffer IP to bring in Differential Pairs. Quick question why is the External Port on in the IP a CLK? Also, when I right click on the port to create an External Interface Port why does it add in _clk_ to the signal name?

The Product Guide is a good reference for our IPs. For the Utility Buffer : https://www.xilinx.com/support/documentation/ip_documentation/util_ds_buf/v2_1/pb043-util-ds-buf.pdf
A common usecase of the utility buffer is to bring differential clocks into the IPI design. It does not imply a clock buffer is used.
When you make the external connection you can remain as works best for your design.
