The signal detect circuit monitors the energy level on the receiver inputs and powers on or off the rest of the high speed data path if a signal is detected or not. By default, each channel allows the signal detect circuit to automatically power on or off the rest of the high speed data path depending on if a signal is present. The signal detect block can be manually controlled in the SMBus channel registers. This can be useful if it is desired manually force channels to be disabled.
