1. A retiming circuit module, adapted to perform signal transmission between an upstream device and a downstream device, the retiming circuit module comprising:
a path control circuit; and
a multipath signal transmission circuit, coupled to the path control circuit, wherein
the multipath signal transmission circuit has built-in first signal transmission path and second signal transmission path,
the multipath signal transmission circuit is configured to perform first signal transmission between the upstream device and the downstream device based on a first signal transmission frequency and the second signal transmission path,
during a period of performing the first signal transmission, the path control circuit is configured to detect a first data sequence transmitted between the upstream device and the downstream device, and
the path control circuit is further configured to control the multipath signal transmission circuit to switch to perform second signal transmission between the upstream device and the downstream device based on the first signal transmission frequency and the first signal transmission path according to the first data sequence,
wherein a signal delay of the first signal transmission path is higher than a signal delay of the second signal transmission path.
