EVM user's guide中有描述：The DS90UB924-Q1EVM board features a 20-position IDC connector for connecting to the FPD-Link (OpenLDI) outputs and a HSD Automotive Connector for connecting an automotive-grade STP cable to
the FPD-Link III input. The included SMA connectors may also be configured as the FPD-Link III data
input, enabling evaluation of other connectors and cable configurations.
也就是说， IDC接口连接FPDlink output，HSD接口和STP cable连接作FPDlink 输入，SMA 接口也可以作为FPDlink的数据输入接口。
