Description
Pericom Semiconductor’s PI3WVR12412 is a multi-standard vid-
eo switch with wide voltage range capability. It supports HDMI
2.0, DisplayPort 1.2, and emerging and proprietary standard.
PI3WVR12412 can pass high-speed signals up to 1.2 V peak-to-
peak differential with a common-mode voltage from 0 to 3.4V for
TMDS signal.
The wide voltage range allow DC-coupled multi-standard opera-
tion. Eliminating AC coupling capacitors saves board space and
improves signal integrity for dense PCB design. The high speed
channels can also pass 0V-3.3V CMOS signals up to 1MHz.
In addition to four high-speed lanes, PI3WVR12412 also switch-
es the DDC and HPD signals or AUX and HPD signals using the
DDC/ AUX and HPD channel mux/demux.
Application
ÎÎRouting of HDMI 2.0 video signals with low signal
attenuation between source and sink for 4K2K ultra high
definition video display and broadcast video equipment.
ÎÎRouting of DisplayPort video signals with low signal
attenuation between source and sink for PC and monitor.
