Back to HDMI / DVI / MHL / DisplayPort Switches


20Gbps DP2.0/HDMI2.1 4 lane 2 to 1 mux/1 to 2 demux


The PI3WVR14412 is a multi-standard video switch with wide voltage range capability. It supports DisplayPort 1.3/1.4/2.0, HDMI 2.1, and emerging and proprietary standards.
The PI3WVR14412 can pass high-speed signals up to 1.2V peak-to-peak differential, with a common-mode voltage from 0 to VDD for TMDS signal. The wide voltage range allows DC-coupled multi-standard operation. Eliminating AC coupling capacitors saves board space and improves signal integrity for dense PCB design. In addition to four high-speed lanes, the PI3WVR14412 also switches the DDC and HPD signals or AUX and HPD signals using the DDC/ AUX and HPD channel mux/demux.
