SIGNAL TRANSMISSION METHOD, DRIVER, AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/153810

Kind Code:

A1

Abstract:

Provided are a signal transmission method, a driver and a system. The driver comprises: the data channel circuit, which is used for implementing equalization-processing-based transparent signal transmission between a first communication device and a second communication device under the action of a current phase-locked loop; and a link adjustment circuit, which is used for acquiring a signal transmitted in the data channel circuit, acquiring link state information according to the acquired signal, configuring an operating parameter of a target phase-locked loop as an operating parameter corresponding to a changed rate where it is determined according to the link state information that the rate of a link needs to be changed, and switching, where it is detected that the link enters a rate-changing state, the phase-locked loop used currently to the target phase-locked loop, wherein the data channel circuit is further used for implementing transparent signal transmission between the first communication device and the second communication device under the action of the target phase-locked loop. By means of the technical solution, the delay in a signal transmission process can be reduced.
