摘要： Provided are a transmission device, a receiving device, and a communication system having a simple configuration and capable of reliably executing the confirmation of a changed bit rate. The communication system 1 sends, to the receiving device 3, a serial data signal Sdata that is set as a constant value across a period of a constant multiple of a cycle of the clock when a bit rate of a serial data signal Sdata in the transmission device 2 is changed. The receiving device 3 that received the serial data signal Sdata receives training data Tdata from the transmission device 2 when it is determined that the serial data signal Sdata is a constant value across a period of a constant multiple of a cycle of the clock, and proceeds to the processing of confirming the changed bit rate.

摘要： A first capacitor is charged by a constant current source circuit for a time corresponding to the delay time of forward pulses. A second capacitor is charged by a constant current source circuit. A comparator compares the voltages of the first and second capacitors, and outputs a timing signal when these voltages match. For this reason, a timing at which the second capacitor has been charged for a time corresponding to the delay time of backward pulses can be obtained.
