5.5.4. Intel® Cyclone® 10 GX 器件的片上I/O匹配

串行(RS)和并行(RT) OCT提供了I/O阻抗匹配和匹配性能。OCT维护信号质量,节省电路板空间并降低外部组件成本。

The Intel® Cyclone® 10 GX devices support OCT in all FPGA I/O banks. For the 3 V I/Os, the I/Os support only OCT without calibration.

图 73. 单端匹配(RS和RT下图显示 Intel® Cyclone® 10 GX 器件中支持的单端匹配方案。RT1和RT2为动态并行匹配,且仅在器件进行接收时使能。双向应用中,RT1和RT2在器件进行接收时自动开启,并在器件进行驱动时自动关闭。
