Patent ID: 7439760

Claim:
An integrated-circuit (IC) die comprising: a. a pad to receive an input signal to the die; b. a receiver having an input terminal coupled to the pad, a reference terminal, and an output terminal; c. a first switch having a first switch node coupled to the reference terminal, a second switch node, and a third switch node, wherein the first switch selectively couples the first switch node to the third switch node and selectively couples the second switch node to the third switch node; d. a first termination impedance coupled between the third switch node and the input terminal; e. a second switch having a fourth switch node coupled to the reference terminal, a fifth switch node, and a sixth switch node, wherein the second switch selectively couples the fourth switch node to the sixth switch node and selectively couples the fifth switch node to the sixth switch node; and f. a second termination impedance coupled between the sixth switch node and the input terminal.
