SDVoE™ Semiconductor Solutions for HDMI Wall Plates
Semtech’s flagship AVP2000T is a truly bidirectional HDMI single chip solution, capable of both transmitting and receiving HDMI 2.0b to support 4K60 over standard IP networks. The part typically consumes around 2.5W, and using optical fiber connectivity to the Ethernet switch, both low power and reduced heat dissipation enable a new class of compact products, such as HDMI wall plate extenders. The challenges of integrating long reach HDMI extension technology into the wall plate form factor can only be met using lower power ASIC-based solutions. The diagram shows an example of room-to-room resource sharing by connecting both sources (game consoles) and sinks (TVs) to the bidirectional HDMI wall plate. With integrated USB-HID connectivity, the AVP2000T also supports the extension of USB devices over IP, such as gaming controller, joysticks, mice and keyboards.
