A common design method of three-line serial communication interface circuit based on optocoupler is introduced in this paper. Circuit design principle and experiment data are analyzed to illuminate the reason of communication error when the transmission rate is increased. In order to resolve transmission error of serial interface circuit based on high-speed optocoupler, several methods are also proposed in the paper. The effectivity and engineering feasibility of these methods are proved by a special experiment. Finally, some valuable suggestions to design three-line serial communication circuit based on high-speed optocoupler are put forward.
