Semiconductor Solutions for Point-to-Point Matrix Switching

Semtech 的 AVX 技术是现有点对点矩阵切换连接 HDBaseT 的完美替代品。AVX 使用标准 IEEE 物理接口和协议提供真正的 4K60 支持,确保通过标准铜缆布线实现最佳的覆盖范围和抗噪性能。当前的扩展矩阵切换连接仅限于 HD,这促使人们转向基于 IP 的系统以支持 4K,但 AV-over-IP 并不总是某些应用的理想选择。例如,室内连接只需要将多达四个信号源切换到壁挂式显示器,而吊装投影机只需要一个简单的矩阵切换。下面基于 AVX 的 4x4 矩阵切换应用图展示了如何使用低成本 AVX100 器件通过铜缆(如 Cat-6a)扩展和切换 HDMI。

AVX for KVM Matrix Switching

作为点对点连接解决方案,AVX 器件不会在 IP 网络上分发视听内容。但 AVX 器件具备一个 1G 以太网接口,可与 SDVoE API 服务器连接到同一网络。API 服务器将发现所有 AVX 端点,包括未连接到网络但通过 10G AVX 链路远程连接的端点。下面的 2x2 AVX 矩阵切换简易系统图对此进行了说明。

如图中的红色箭头所示,客户端软件可通过本地矩阵切换器和远程 AVX 链路监测和控制 AVX 器件。如前所述,AVX 在 AVX 链路上的器件之间仍使用标准 IP 协议。同一网络中可能存在其他服务器,以拦截连接到远程 AVX 端点的 USB 器件生成的 USB 流量。这些器件用于高级 KVM 应用,如单用户控制多个主机。得益于 SDVoE API 的灵活性,任何为 AVX 开发的软件都可以重新利用或按原样再用于基于 AVP 的解决方案,从而大大降低开发成本,并为最终用户提供灵活、通用的控制集,适用于点对点视听扩展和 SDVoE AV-over-IP 系统。

For the most cost-effective point-to-point matrix switch solution, providing the lowest end-to-end latency performance, Semtech’s AVX100 AV Extender can be used to transmit up to 4K60 video over 100m of Cat-6a standard copper category cabling. When paired with an industry standard 10GBaseT PHY, only a handful of core components are needed to implement the complete AVX Transmitter solution.

Similarly, the AVX100 can be used to power the AVX Receiver, providing an end-to-end solution with sub-millisecond latency for high performance matrix switch applications using copper category cabling. As a single chip solution for both Transmitter and Receivers, the AVX100 can also be dynamically switched between Transmitter and Receiver operation, allowing single hardware designs to be configurable at install.
