Abstract: A receiver is provided. The receives includes: a signal detection circuit configured to receive differential signals having a variable data rate, and provide a detection signal based on the differential signals corresponding to a first data pattern of a first frequency, wherein the first data pattern of the first frequency indicates an exit from an electrical idle state; an analog-digital converter circuit configured to generate sample data by sampling the differential signals at a second frequency, and identify whether the sample data corresponds to a second data pattern which indicates normal data; and a control circuit configured to enable the analog-digital converter circuit based on the detection signal, and store the sample data. The first frequency is lower than the second frequency.
