Product 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-topeak 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.


  • 4-lane, 1:2 mux/demux that will support RBR, HBR1, or HBR2
  • Data rate: 3.4 Gbps to 6.0 Gbps for high data channels
  • Supports DDC with HPD channel mux/demux @ HDMI
  • Supports 720 Mbps high-speed DP AUX @ DP
  • -1.7 dB Insertion Loss for Dx channels @ 3.0 GHz
  • -3 dB Bandwidth for Dx channels: 4.8 GHz
  • Return loss for Dx channels @ 3.0 GHz: -16 dB
  • Low Crosstalk for high speed channels: -25 dB@6.0 Gbps
  • Low Off Isolation for high speed channels: -22dB@6.0 Gbps
  • Low channel-to-channel skew, 35ps max
  • Low Bit-to-Bit Skew, 5ps typ (between '+' and '-' bits)
  • VDD Operating Range: 3.3V +/-10%
  • ESD Tolerance: 2kV HBM
  • Packaging (Pb-free & Green): 42 TQFN (ZHE)


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