DAC38J84EVM: SYNC信号无法通过FMC-LHC接口输入到FPGA

Part Number: DAC38J84EVM

你好:

我在使用一块第三方的alinx xczu9eg ultrascale+mpsoc开发板进行基于JESD204B的DA开发.

我现在使用的FMC子板是DAC38J84EVM , 其中DAC芯片的同步信号SYNCBP/N连接到FMC的F10,F11接口.

但是在FMC-LPC中,f排没有接到FPGA上去.

DAC的数据表中写

SYNCBP B7 O Synchronization request to transmitter, LVDS positive output. It can be left open if not used

我想知道,我应该怎么操作?有别的办法能够使我继续在这块alinx开发板上继续我的开发吗?

祝好
