The invention discloses an asynchronous eye pattern equalization method. The method comprises the steps of obtaining eye pattern signal data; enabling the equalizer to adopt j equalization gears to perform undersampling on the eye pattern signal data to obtain equalized data, setting i levels of reference levels according to the amplitude of the equalized data, and preprocessing the equalized data according to each level of reference level to obtain eye pattern statistical data corresponding to all levels of reference levels of the j equalization gears; screening the eye pattern statistical data corresponding to all levels of reference levels of the j equalization gears according to a preset condition to obtain adjusted equalization gears; and outputting the adjusted equalization gear to the equalizer so that the equalizer performs adaptive equalization gear adjustment, wherein i and j are integers, j is greater than or equal to 2, and i is greater than or equal to 8 and less than or equal to 64, so that frequency and channel adaptive equalization compensation can be provided for actual attenuation generated by different data rates and channels, the power consumption waste is reduced, and the efficiency is improved. The invention discloses an asynchronous eye pattern balancing device and system.
Description
technical field [0001] The present invention is in the technical field of design signal transmission, and in particular relates to an asynchronous eye pattern equalization method, device and system. Background technique [0002] With the development of communication technology and computer technology, the amount of data transmission and exchange between different devices is increasing day by day. The main limiting factor affecting data transmission is the interface rate between different devices. High-speed serial interface has become an inevitable choice for high-speed data transmission. Key performance indicators for high-speed serial interfaces include transfer rate, eye diagram performance, bit error rate, and data jitter. However, the non-ideal factors of the wired transmission channel will lead to channel noise and frequency attenuation, seriously reduce the quality of the received signal, limit the signal transmission rate and the length of the communication link, and...
