A product Line of Diodes Incorporated PI3WVR12412 HDMI 2.0, DisplayPort 1.2 Video Switch Features Description 4-lane, 1:2 mux/demux that will support RBR, HBR1, or e PTh I3WVR12412 is a multi-standard video switch with wide HBR2 voltage range capability. It supports HDMI 2.0, DisplayPort 1.2, and emerging and proprietary standard. Data rate: 3.4 Gbps to 6.0 Gbps for high data channels PI 3W V R 12 412 c a n p a s s h i g h- s p e e d si g n a l s up to 1. 2 V Supports DDC with HPD channel mux/demux HDMI peak-to-peak differential with a common-mode voltage from 0 to Supports 720 Mbps high-speed DP AUX DP 3.4V for TMDS signal. -1.7 dB Insertion Loss for Dx channels 3.0 GHz e Th w id e volt a ge r a nge a l low D C - c ouple d mu lt i- s t a nd a rd -3 dB Bandwidth for Dx channels: 4.8 GHz operation. Eliminating AC coupling capacitors saves board space Return loss for Dx channels 3.0 GHz: -16 dB and improves signal integrity for dense PCB design. The high speed channels can also pass 0V-3.3V CMOS signals up to 1MHz. Low Crosstalk for high speed channels: -25 dB 6.0 Gbps Low Off Isolation for high speed channels: -22dB 6.0 Gbps I n a d d it ion to fou r h i g h- s p e e d l a ne s , PI 3W V R 12 412 a l s o switches the DDC and HPD signals or AUX and HPD signals Low channel-to-channel skew, 35ps max using the DDC/ AUX and HPD channel mux/demux. Low Bit-to-Bit Skew, 5ps typ (between + and - bits) V Operating Range: 3.3V +/-10% DD Application ESD Tolerance: 2kV HBM Routing of HDMI 2.0 video signals with low signal attenuation between source and sink for 4K2K ultra high definition video Packaging (Pb-free & Green): 42 TQFN (ZHE) display and broadcast video equipment. Routing of DisplayPort video signals with low signal attenuation between source and sink for PC and monitor.
