Abstract
A method and apparatus electrically disconnects termination on a differential transmission bus. A switchable impedance matching termination apparatus is provided including a terminating resistor network for terminating at least one pair of a plurality of differential signal line pairs. An enabling signal input is also provided. Further, the invention has a first signal network interconnected between the enabling signal input and the terminating resistor network. Also provided is a second signal network interconnected between the enabling signal input and the terminating network wherein the first and second signal networks are responsive to the signal. The response is designed to terminate the at least one pair of the plurality of differential signal line pairs. A method is also provided for disconnecting terminating resistors on a device having a differential transmission line.
