Diodes Incorporated has expanded its video passive multiplexer/demultiplexer (mux/demux) switch portfolio with the introduction of the 4-channel PI3WVR14412.
Supporting up to 20Gbps operation, this 2:1/1:2 mux/demux device enables the routing of 4K high definition (HD) and 8K ultra-high definition (UHD) video signals while exhibiting extremely low signal attenuation. This routing can either be from two sources to a single sink or conversely a single source to dual sinks.
PI3WVR14412 is fully compliant with both the DisplayPort 2.0 and HDMI2.1 interface standards, which are featured in the latest generation of graphics processor units (GPUs).
Bidirectional communication is provided via the AUX channel. This means that other protocols like USB 2.0 can be supported, thereby avoiding the need for additional cabling to the host and reducing overall system costs. The wide input signal voltage range covered (0V to 3.6V) allows direct coupling of HDMI at VDD bias and DP signals at 0 bias.
Key applications are mobile workstations, games consoles, docking systems, notebook computers, monitors, TVs, and set-top boxes.
