| abstract |
A serial communication device includes a serializer configured to transmit serial data for each channel via a transmission line for the corresponding channel, and a deserializer configured to receive the serial data. The serializer includes a transmission processing circuit that creates a protocol where pieces of valid data are inserted between a start frame and an end frame for each channel. The deserializer includes buffers for the respective channels to detect the start frame of each channel, store the valid data in the corresponding buffer, set, as a to-be-processed buffer, at least one buffer that stores the valid data on a channel to be deskewed, start externally transferring data from the to-be-processed buffer when a fixed amount of the valid data is stored or when the end frame is detected, detect a boundary between the valid data and the end frame, and extract the valid data from the to-be-processed buffer. |
