Description
Pericom Semiconductor’s PI3WVR12612 is a multi-standard
video switch with wide voltage range capability. It supports
DisplayPort 1.2, HDMI 2.0, and emerging and proprietary standards.
PI3WVR12612 can pass high-speed signals up to 1.2 V peak-
to-peak differential with a common-mode voltage from 0 to
3.4V. The wide voltage range allows DC-coupled multi-standard
operation. Eliminating AC coupling capacitors saves board space
and improves signal integrity for dense PCB designs.
The high speed channels can also pass 0V-3.3V CMOS signals up
to 1MHz.
In addition to four high-speed lanes, PI3WVR12612 also switch-
es AUX, DDC, and HPD signals.
Application
Routing of DisplayPort and HDMI signals with low signal at-
tenuation between source and sink.
