Abstract
A communication control device includes: a first processing unit that converts an electrical signal received by a communication channel into digital data and outputs the digital data, and in a second operation mode in which an amount of power supplied to the communication control device is lower than in a first operation mode, outputs a notification signal upon receiving an electrical signal indicating an arrival of packet data; a clock controller that, in the second operation mode, initiates supplying a clock signal upon receiving the notification signal; and a second processing unit that (i) has a receiving unit that extracts packet data from the digital data and outputs the extracted packet data, and (ii) in the second operation mode, stops receiving packet data during a time that the clock signal is not supplied, and upon reception of the clock signal, starts receiving packet data using the received clock signal.
