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 Î ÎRouting 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. Î Î Routing of DisplayPort video signals with low signal attenuation between source and sink for PC and monitor.
