工程的配置如下所示：
JESD204B模式：采用模式11；
JESD204B的Line数量：使用了8个line（前4个为I、后4个为Q）；
JESD204B数据率：数据率为2.6GSPS（I/Q）；
全链路内插值：通道旁路（内插1）、主通道内插4、主通道NCO设置为50MHz
ADC速率：10.4GSPS
参考时钟：325MHz
SYSREF：20.3125MHz
锁相环配置：使能PLL，N=8，M=2
在当前配置下，输入了1个5MHz的正弦波（格式已按照手册格式排好），应该输出一个55MHz的正弦波，但实际无输出，此时204B已经建链，且FPGA已观测到数据输出到204B端口；当修改为NCO Only模式时，则能够输出50MHz的正弦波，不知在参数配置方面是不是哪里配错了，下面是在正常输入下的参数配置步骤，希望得到大家的指点：
