针对视频应用：虚拟现实、增强现实和数码相机等新应用需要拓展应用处理器上的摄像头或显示接口数量。

连接CrossLink和CrossLink-NX：莱迪思CrossLink和CrossLin-NX FPGA系列结合了FPGA的灵活性与高性能的硬核D-PHY端口，非常适合解决各类视频桥接、聚合和ISP设计难题。

完整的参考设计：基于CrossLink和CrossLin-NX器件的1：N MIPI CSI-2/DSI复制器参考设计为一个或两个通道输出提供了输入通道的副本。

特性

  • 一个RX通道复制到一个或两个TX通道（RX/TX通道可以有一个、两个或四个lane）
  • 对于RX，硬核IP能实现每通道1.5 Gbps的速率并节省FPGA资源；软IP性能则为1.2 Gbps
  • 硬IP用于TX通道，每条lane性能可达1.5 Gbps
  • 如果连续时钟可以从内部获得或直接由引脚提供，则可以在RX通道上使用非连续时钟模式。
  • Tx每条lane最高为1.5 Gbps（最大带宽10 Gbps）
