Abstract
P and N termination networks couple a P line and an N line to corresponding receiver inputs. Each termination network includes an electrostatic discharge protection T-coil having an input port coupled to the corresponding line, a terminal port, and a center tap port. At least one of the termination networks further includes at least one delay T-coil having a terminal port, a center tap port, and an input port coupled to the terminal port of a corresponding one of the electrostatic discharge protection T-coils. In a no delay mode, a multiplexer selectively connects the P and N electrostatic discharge protection T-coil center tap ports to the P and N inputs of the receiver. In a delay mode, the multiplexer selectively connects the delay T-coil center tap port to a corresponding one of the P input of the receiver and the N input of the receiver.
