Patent attributes
The invention is a serial communication device for receiving serial data and sampling the serial data with synchronizing with communication clocks. The device has a clock generation unit for dividing a reference clock according to a predetermined dividing value, generating the communication clock each time the number of dividing value of the reference clock is generated, and generating a supplemental clock at any timing of the reference clock between adjacent communication clock; and a data decision circuit for receiving serial data, sampling 1-bit data at sampling timings including at least the adjacent communication clocks and the supplemental clock therebetween, and deciding the 1-bit data according to the decision by majority of the plurality of the sampling data which is sampled.
