1. An integrated-circuit die comprising:
a receiver having an input terminal and an output terminal;
a first switch having a first node coupled to a reference, a second node, and a third node, wherein the first switch selectively couples the first node to the third node and selectively couples the second node to the third node;
a first termination element coupled between the third node and the input terminal;
a second switch having a fourth node coupled to the reference, a fifth node, and a sixth node, wherein the second switch selectively couples the fourth node to the sixth node and selectively couples the fifth node to the sixth node; and
a second termination element coupled between the sixth node and the input terminal.
