High-speed serial transmission data phase alignment method, storage medium and terminal equipment

Abstract

The invention belongs to a phase alignment method. The method solves the problems that according to a phase alignment method commonly adopted at present, if the total delay provided by a delay module is not enough and a wrong effective window ending position is easy to find, and even if the starting position and the ending position of an effective window can be found in the total delay provided by the delay module, the time for completing phase alignment is not controlled, and the operation time is long. The invention provides a high-speed serial transmission data phase alignment method, a computer readable storage medium and terminal equipment. By traversing the n time delay units of the time delay module, the time delay required during phase alignment can be determined according to the indication bit sequence form corresponding to the n time delay units of the time delay module. Therefore, the time delay required during phase alignment is determined, the requirement for the time delay range of the time delay module is low, the execution efficiency is higher, and the steps of the phase alignment method can be executed on the computer readable storage medium and the terminal equipment.

Description

technical field [0001] The invention belongs to a phase alignment method, in particular to a phase alignment method for high-speed serial transmission data, a computer-readable storage medium and terminal equipment. Background technique [0002] High-speed serial data transmission occupies an important position and is widely used in high-speed network transmission, high-speed radar detection, high-speed data transmission, high-speed detectors and other fields. However, the delay difference inside the chip and the PCB trace difference will cause an unknown phase difference between the sampling clock and the high-speed serial data, which will cause the sampling clock to collect wrong data at an inappropriate position. Therefore, it is necessary to phase-align the sampling clock and data during high-speed serial data transmission. [0003] At present, the commonly used phase alignment method is to find the start position and end position of the effective window of the data eye...

Problems solved by technology

[0004] The present invention solves the phase alignment method commonly used at present. If the total delay provided by the delay module is not enough, it is easy to find the wrong end position of the effective window, even if the beginning of the effective window can be found within the total delay provided by the delay module. Position and end position, the time to complete the phase alignment is not controlled, and the technical problem is that it takes a long time to provide a high-speed serial transmission data phase alignment method, computer-readable storage medium and terminal equipment
