PI3WVR12412
Wide Voltage Range DisplayPort™ & HDMI Video Switch
Pericom Semiconductor’s PI3WVR12412 is a multi-standard
video switch with wide voltage range capability. It supports
DisplayPort™1.2, HDMI 1.4, and emerging and proprietary
standards.
The 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. The wide voltage range allows DC-coupled
multi-standard operation. Eliminating AC coupling capaci-
tors saves board space and improves signal integrity for
dense PCB designs.
In addition to four high-speed lanes, PI3WVR12412 also
switches AUX and HPD signals.
Application
Routing of DisplayPort and HDMI signals with low signal
attenuation between source and sink.
