20 Gbps multi-channel mux/demux
Mux/demux facilitates better HD/UHD video signal routing with 35 percent increase in speed compared to competitive devices.

Diodes Incorporated has further expanded its video passive multiplexer/demultiplexer (mux/demux) switch portfolio with the introduction of the 4-channel PI3WVR14412. Supporting up to 20 Gbps operation, this 2:1/1:2 mux/demux device provides speeds beyond those of other products — resulting in a 35% increase compared to competitive devices.

The PI3WVR14412 mux/demux 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). Key applications are mobile workstations, games consoles, docking systems, notebook computers, monitors, TVs, and set-top boxes.

The PI3WVR14412 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.

Use of proprietary technology is responsible for the elevated speeds attained by the PI3WVR14412. The high-speed channels of this device are also able to maintain industry-leading signal integrity characteristics. When running at 10 GHz, a -2 dB insertion loss and a -10 dB return loss are typically witnessed. The channel-to-channel crosstalk is just -35 dB and off isolation is -15 dB at this frequency. Bit-to-bit skew is normally only 5 ps.
