The 7 series FPGAs GTX and GTH transceivers are power-efficient transceivers, supporting line rates from 500 Mb/s to 12.5 Gb/s for GTX transceivers and 13.1 Gb/s for GTH transceivers. Four GTXE2_CHANNEL primitives and one GTXE2_COMMON primitive to be a Quad. GTX收发器的TX RX相互独立,但...
当Xilinx 7Series FPGA中,存在3种主要的时钟网络:BUFG,BUFR,BUFIO以及他们所衍生出的各种变种。那么他们有什么主要特点和区别呢? BUFIO是IO时钟网络,顾名思义,它只能驱动IO Block里面的逻辑,不能驱动CLB里面的LUT,REG等逻辑。BUFIO可以被如下节点驱动: 1、SRCCs and MRCCs in the same clockregion 2、MR...x...
