我查看原理图首页框图标注FMC,但引脚定义似乎与普通fmc不同:
第一图为ADC12DL3200EVM,A1 A2是一对差分对,图2是Xilinx KC705的fmc接口,A2 A3是一对,是否代表不能兼容

您好,ADC12DL3200EVM是标准的FMC接口,A1A2....只是引脚排列的名称,不一定是一一对应的,只要都是FMC接口就是可以兼容的。
另外和您确认下,您指的Xilinx KC705的fmc接口是LPC还是HPC的?我要看下ADC12DL3200EVM的FMC接口是LPC还是HPC的 ,从而确定是否和FPGA能直接连接。
您好抱歉回复晚了。关于这个问题,我这边收到的回复如下:
I'm not familiar with LPC/HPC definitions for LVDS pairs on this FMC connector - I am only familiar with these terms when referring to JESD serdes lanes and routing. Regardless of the terminology, please find the ADC12DL3200EVM FMC pinout below.
KC705's J22 connector is referring to JESD serdes pairs, indicated by DPx_C2M_x and DPx_M2C_x.
