CH-1536TX - HDMI/Audio over CAT5e/6/7 Transmitter with 48V PoH

This HDMI over single Cat.5e/6/7 Transmitter and Receiver set is a great solution for extending uncompressed HD audio and video as well as Ethernet and control via a single run of Cat.5e/6/7 cable over distances of up to 100 meters. Multiple data and control interfaces are provided, including IR, RS-232 and LAN connections.

This extender set complies with the advanced HDCP 2.2 and HDMI 2.0 standards, as well as supporting the legacy HDCP 1.x and HDMI 1.x standards. Despite HDBaseT’s 10Gbps bandwidth limitation, 4K UHD HDMI video, up to and including 4K@60Hz (4:4:4), is able to be processed and extended by subsampling 4:4:4 color to 4:2:0 and reducing bit depth when necessary.

Beyond video, data, and control these units also feature useful audio features. The Optical Audio Return (OAR) feature supports transmitting optical audio from the Receiver side to the Transmitter side for local playback. An audio insertion feature is also included, allowing for stereo analog audio to be embedded into the HDMI output signal. Rounding out the feature set is robust EDID management as well as automatic HDBaseT clock stretching and TMDS re-clocking support. The Receiver (PD) is powered by 48V PoH provided by the Transmitter (PSE), allowing for greater flexibility within different installation scenarios.
