USB Powered HDMI® Voltage Inserter
USB to HDMI voltage inserter that provides stable 5V power and up to 500mA current for bus-powered HDMI accessories
The C2G CG42236 is an active voltage inserter designed to support HDMI bus-powered devices that require more current than a standard source can provide. Standard HDMI sources like computers, media players, or teleconferencing codecs typically only deliver a 55mA hot plug supply according to HDMI standards. When accessories like HDMI extenders, active cables with embedded chipsets, or signal-sensing auto-switching devices demand more current, the system can experience flashing images, HDCP authentication errors, or a total loss of video. The CG42236 solves this by isolating the power from the source device and delivering a stable 5V signal and up to 500mA of dedicated current. This ensures the necessary electrical handshake for HDCP key authentication, EDID information exchange, and hot plug connection detection remains intact. This device is fully compliant with all UltraHD and 4K performance requirements.
