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 peakto-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 switches AUX, DDC, and HPD signals.
Application
Routing of DisplayPort and HDMI signals with low signal attenuation between source and sink.
