用于 HDMI 墙板的 SDVoE 半导体解决方案

Semtech 的旗舰产品 AVP2000T 是真正的双向 HDMI 单芯片解决方案,能够传输和接收 HDMI 2.0b,可在标准 IP 网络上支持 4K60。该部件的功耗通常约为 2.5W,并且使用光纤连接到以太网交换机,低功耗和更少的散热使新型紧凑型产品成为可能,例如 HDMI 墙板扩展器。长距离 HDMI 扩展技术难以集成到墙板中,只有使用基于 ASIC 的低功耗解决方案才能解决这个问题。该图示为通过将源(游戏机)和接收器(电视)连接到双向 HDMI 墙板来实现房间到房间的资源共享。由于集成 USB-HID 连接,AVP2000T 还支持通过 IP 扩展 USB 器件,例如游戏控制器、游戏操纵杆、鼠标和键盘。

Inside the Box with AVP2000T: An Elegant AV-over-IP Wall Plate Transceiver Solution

Taking advantage of the full-duplex nature of Ethernet, the AVP2000T Transceiver can be streaming uncompressed quality 4K60 video with multichannel digital over IP networks, while also receiving 4K60 video and audio from the network. With just a handful of essential components, as shown in the diagram, a single HDMI wall plate can support both HDMI input and output connectivity along with USB. Pairing the AVP2000T with a standard SFP+ optical module allows unprecedented reach performance, supporting distances of up to 400m using low cost multimode fiber, or tens of kilometers with single mode fiber. Given the key benefits of size and weight of optical fiber, plus immunity to electromagnetic interference (EMI), AV signal distribution in space sensitive or electrically noisy environments is possible without any compromise to signal integrity and visual performance.
