New ContributorQuestion about F-Tile FHT Reference Clock
为什么F-Tile的FHT用过QSFP-112（400G光口，4*112Gbps）接口的时候需要两路参考时钟？其中一路参考时钟输入给REFCLK_FHTL12A，一路是需要输入给REFCLK_FGTL12A吗？
如下图所示的设计连接是否可行？

Why does F-Tile's FHT need two reference clocks when it uses QSFP-112 (400G optical port, 4*112Gbps) interface? One of the reference clocks is input to REFCLK_FHTL12A. Does the other one need to be input to REFCLK_FGTL12A?
Is the design connection shown in the picture below feasible?
