Abstract:
A data transmission circuit transmitting an activation signal prior to a data signal through a signal transmission line, including: an activation detection signal generation unit for generating an activation detection signal by detecting the activation signal; and a wakeup signal generation unit for being activated by the activation detection signal, and generating a wakeup signal by detecting that the activation signal is transmitted for a predetermined time.
