20Gbps 1:2 Signal Switch For DP2.1, HDMI2.1, MIPI DPHY/CPHY, USB3.2


The PI3WVR14412Q is a multi-standard video switch with wide voltage range capability. It supports DisplayPort 1.3/1.4/2.1, HDMI 1.4/2.0/2.1, MIPI DPHY/CPHY, USB3.2, and emerging and proprietary standards.

The PI3WVR14412Q 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 PI3WVR14412Q also switches the DDC and HPD signals or AUX and HPD signals using the DDC/ AUX and HPD channel switch.
