Abstract:
1. A device for communication with a second device via differential signal lines, the device comprising: a controller; one or more first switches in communication with the controller and configured to connect, during at least a part of a power-save mode in response to receiving at least one signal indicative of the power-save mode from the controller, low-impedance to a first differential signal line and to maintain voltage on the first differential signal line to the second device to be less than complementary voltages used during signaling with the second device; and one or more second switches in communication with the controller and configured to connect, during the at least a part of a power-save mode in response to receiving the at least one signal from the controller, low impedance to a second differential signal line and to maintain voltage on the second differential signal line to the second device to be less than complementary voltages used during signaling with the second device.
