PURPOSE:To attain synchronous communication by providing a frequency division circuit for character synchronization to the transmission side and providing a frequency division circuit for character synchronizing and a reception control section detecting a synchronizing character to the reception size to apply character synchronization at initial transmission only. CONSTITUTION:A synchronous communication equipment consists of a reception buffer means 4 using a synchronizing clock to fetch a serial data and storing it while shifting it sequentially, a synchronizing character detection means 9 detecting a synchronizing character from the serial data stored in the reception buffer means and a frequency division counting sequentially a synchronizing clock for bit number constituting a data and applying frequency division after the synchronizing character detection means is used to detect the synchronizing character. Then the reception buffer means 4 is synchronized one to one with the frequency division output of the frequency division means and the fetched serial data is outputted through an internal data bus in bit parallel. |
