Multi-channel lvds data processing device and method

Abstract

The invention discloses a multi-path LVDS data processing device and method. The method comprises the following steps: converting an introduced external synchronous clock into a sampling clock capableof dynamically configuring phases of multi-path LVDS data; acquiring multiple paths of low-voltage differential signal LVDS data according to the sampling clock, and synchronizing the multiple pathsof LVDS data; and transmitting the multiple paths of LVDS data after synchronization; and processing and buffering the multiple paths of LVDS data after synchronization. The synchronous clock phase ina whole period can be dynamically configured to obtain the optimal phase value, the limitation of LVDS data delay adjustment is effectively avoided, the stability of multi-path LVDS data acquisitionis improved, no physical connection is needed, and the data transmission sequence is flexible and variable. Interface channels can be dynamically increased as required; synchronous acquisition, sorting processing and high-speed transmission can be carried out on multiple paths of LVDS data, the data processing time is shortened, and the data processing efficiency is improved.

Description

Technical field[0001]The invention relates to the technical field of data processing and transmission, in particular to a multi-channel LVDS data processing device and method.Background technique[0002]With the development of communication systems, the requirements for multi-channel and high-speed data transmission are getting higher and higher; high-speed data transmission interfaces mostly use Field Programmable Gate Array (Field Programmable Gate Array, FPGA) transceivers. However, FPGA chips are generally more expensive, especially when multiple channels are required to have Tranceiver; therefore, low-voltage differential signaling (LVDS) transmission is more costly on the basis of coping with multiple high-speed transmissions. Advantage.[0003]LVDS is a differential signal technology with low power consumption, low bit error rate, low crosstalk and low radiation. This transmission technology can transmit serial data at speeds of up to thousands of Mbps. The core of LVDS technolog...
