1. An electronic device, comprising:
an input interface for receiving an input signal;
a signal conditioning circuit coupled to the input interface, wherein the signal conditioning circuit is configured to be disabled and consume power below a first threshold power level in a low power mode;
a first signal detector coupled to the signal conditioning circuit, wherein the first signal detector is configured to monitor a differential mode component of the input signal for controlling the signal conditioning circuit to exit the low power mode; and
a second signal detector coupled to the first signal detector, the second signal detector configured to, in the low power mode, detect a start of the input signal and enable the first signal detector based on a common mode component of the input signal.
