Abstract
This application relates to the field of vehicle data transmission technology, specifically to a SerDes data transmission system, control method, chip, and vehicle. It aims to solve the problem of maintaining bidirectional data transmission between the serializer and deserializer even after the high-speed forward data transmission channel and the low-speed reverse data transmission channel malfunction. To this end, this application proposes a three-element SerDes data transmission architecture consisting of a high-speed forward data transmission channel, a low-speed reverse data transmission channel, and a low-speed bidirectional data transmission channel. By adding a lower-speed bidirectional data transmission channel, bidirectional data transmission between the serializer and deserializer can still be maintained even when the high-speed forward and reverse data transmission channels malfunction. This enables online rapid fault diagnosis, fault assessment, and fault repair, improving the reliability of SerDes data transmission, enhancing the user experience, and facilitating vehicle development, testing, and after-sales maintenance.
