Abstract

Communication devices and systems are disclosed. In one example, a communication device includes a LINK that performs protocol conversion of a signal from a Master and outputs the converted signal to a Slave SerDes, and of a signal from the Slave SerDes and outputs the converted signal to the Master. The LINK alternatively selects a first mode and a second mode. In the first mode, the LINK converts a 1-byte signal transmitted from the Master into a signal of a first communication standard in units of the 1-byte signal and transmits the converted signal to the Slave SerDes, then receives a signal of the first communication standard including an ACK signal representing an acknowledgement or a NACK signal representing a negative acknowledgement, and converts the received signal into a signal of a second communication standard and transmits the converted signal to the Master.
