PI3WVR12612
Wide Voltage Range DisplayPort™ & HDMI Video Switch
Pericom Semiconductor’s PI3WVR12612 is a multi-standard
video switch with wide voltage range capability. It supports
DisplayPort
™
1.2, HDMI 1.4, and emerging and proprietary
standards.
PI3WVR12612 can pass high-speed signals up to 1.2V
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.
In addition to four high-speed lanes, PI3WVR12612 also
switches AUX, DDC, and HPD signals.
Application
Routing of DisplayPort and HDMI signals with low signal at-
tenuation between source and sink.
