Abstract

Methods for detecting one or more signals at a PCI Express interface includes receiving, a signal by a receiver at the PCI Express interface. The methods further include identifying one or more data sampling points to set an amplitude threshold. Further, the method includes comparing an amplitude of the received signal with the amplitude threshold. The method also includes confirming that the received signal is a valid signal when the amplitude of the signal is at least one of greater than or equal to the amplitude threshold over a predefined period of time. The method also includes disabling a signal detector of the PCI Express interface to save power. The signal detector is configured to detect one or more low frequency signals; and testing whether the detected signal is correct.
