多路基于TLK2711高速串行图像数据的传输系统
Design of multi channel high-speed serial image data transmission system based on TLK2711
摘要
Abstract
In order to improve the utilization rate of FPGA IO for multi-channel high-speed serial image data transmission in the space application ,and to overcome the relative phase uncertainty of the received multi-channel parallel recovery data ,we propose a new design of multi-channel high-speed se-rial image data transmission system based on TLK2711 .One new method is using the clock buffer simultaneously to provide low jitter clock for the multi-channel TLK2711 and FPGA .For serial data transmission ,the FPGA internal component digital clock management unit (DCM ) is used to adjust the phase ,the TLK2711 internal loopback function are carried out for the data and clock phase of the dynamic adaptive adjustment .For serial data reception ,high-speed asynchronous data cache is used for data conditioning and meets the Camera Link interface protocol ultimately .The output data have the same reference clock ,though the input data have uncertain phase relationship .The experimental results show that the clock buffer can reduce clock jitter ,the transmission system is stable and relia-ble ,the maximum transmission rate is up to 6.8 Gbit/s .This method can greatly improve the resource utilization rate within the FPGA and realize the relative stable phase of the multi-channel parallel re-covery data to meet the high stability transmission requirements of the multi-channel TLK2711based on high-speed serial data .关键词
