BIDIRECTIONAL TRANSMISSION SYSTEM, SERIALIZER CIRCUIT, DESERIALIZER CIRCUIT, AND AUTOMOBILE

摘要

To provide a bidirectional transmission system which can automatically optimize the operation parameter of a circuit.SOLUTION: A first receiver 204 receives second serial data D2S transmitted from a second circuit 300. A second receiver 302 receives first serial data D1S transmitted from a first circuit 200. An automatic adjustment circuit 304 generates a control signal CTRL1 so that an error rate of the first serial data D1S received by the second receiver 302 is reduced. A second driver 306 drives a differential transmission line 102 according to the second serial data D2S which includes the control signal CTRL1. The operation parameter of the first driver 202 is set on the basis of the control signal CTRL1 included in the second serial data D2S.SELECTED DRAWING: Figure 1
