Abstract
A demodulation circuit can demodulate a serial data and an infrared data and can discriminate between the serial data and the infrared data. An edge detection circuit detects an edge of an infrared input and the edge signal and the serial data are taken by an OR circuit. An OR output and a total tap number signal are input to a LPF. The LPF has a function for outputting a demodulation output signal and the operation execution signal. By the operation execution signal, demodulation of the infrared input and demodulation of the serial input are discriminated by a data discrimination circuit. By this, an UART for reproducing the infrared data and the serial data is not required separately and can be made common.
