    我在电路板上使用AD9154。Fdac=2GHz，4x插值。数据速率500MHz，输入时钟为250MHz，SYSREF频率15.625MHz，JESD204B通道速率5Gbps。
    

     
    

    单链接模式0，LMFS=8411.
    

     
    
										

    
				配置完成后，sync经常拉低。DAC PLL和SERDES PLL都已经锁定。
读取x47B，提示CMM中断有效。
x470~473寄存器，473一直为0，ILAS没有通过。
读取400~40D，M、N、NP这些参数 FPGA中使用了默认值，没有配置，与9154中设置的不一致，不知道这些会不会影响？
从我们之前调试AD9176，FPGA中只设置了F、K，其他参数使用默认值，AD9176链路都是正常的。
