Description
The PI3WVR12412 is a multi-standard video 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
operation. 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
switches the DDC and HPD signals or AUX and HPD signals
using the DDC/ AUX and HPD channel mux/demux.
