ABSTRACT:
In a receiver circuit that receives data and clock signals through the cables, the number of transitions of a signal obtained based on the data or clock signal is detected by a frequency detection circuit, and when the number of transitions is not more than a predetermined set value, a signal for resetting the operation of a serial-parallel converter circuit included in a data processing unit is output, so as to control the output of received data. Thus, disconnection of the cable can be detected with low power consumption without providing a pull-up resistor and pull-down resistor and noise resistance can be improved.
