An electronic device includes a power line communication circuit configured to perform power line communication with an external device, the power line communication circuit including: a power line switch provided between a regulator output node and a POGO output node; and a pull-up resistance provided between the POGO output node and a power supply voltage; and a processor configured to control the power line communication circuit, wherein the processor is further configured to: based on receiving a start signal instructing an initiation of high-speed communication, turn off the power line switch to block an electrical coupling between the regulator output node and the POGO output node, and perform the high-speed communication with the external device by connecting coupling the POGO output node to the power supply voltage through the pull-up resistance or connecting coupling the POGO output node to a ground voltage, based on according to output data.

Electronic device performing high-speed power line communication and operating method thereof

A mobile device includes; a power line communication ( ) module that communicates data with an external device via a power line, receives a first preamble signal from the external device during a first preamble interval, receives a voltage signal as the data during a data reception interval following the first preamble interval, and demodulates the voltage signal to provide a demodulated voltage signal, a frequency/duty detector that detects a frequency and a duty of the first preamble signal, and a control circuit that performs signal a data determination operation on a demodulated voltage signal during a data period and using the first detected frequency and the first detected duty.
