ABSTRACT

In the case of the high-speed serial data transmission method, the unidirectional main channel is mainly used. However, in order to overcome the disadvantages of this method, an auxiliary channel capable of bidirectional communication is used. In this paper, we propose a method to maintain the clock of the sink to serve as the auxiliary channel by utilizing the idle time of the main channel, and also propose a bidirectional communication technique using this method. During idle time, the sink's clock-retention device is used to send data to the source and the source can detect the data with the over-sampling technique. As a result, this approach can reduce the EMI / EMC and does not require additional circuit area and power consumption.
