ABSTRACT

As the data transmission speed increases, the source transmits the clock and data together, and the CDR(Clock Data Recovery) of the sink restores the clock Some communication schemes include unidirectional channels that transmit data from sink to source, or bidirectional channels between source and sink. However, the bidirectional channel transmits data at a relatively low speed as compared with the unidirectional channel, and additional circuitry is required to separately generate the transmission clock. In this paper, we propose a new bidirectional communication method that does not require a CDR circuit to recover the transmitted data from the source using the clock recovered from the sink. As a result, it becomes possible to utilize a unidirectional channel as a bidirectional channel without increasing the additional circuit area and power consumption at the source.
