PI3WVR31212A DP/HDMI 1:2 De-multiplexer switches Features ÎÎDP/HDMI 1:2 De-multiplexer switch with 4 high speed differential channel and AUX/DDC, HPD and CAB_DET signal channels ÎÎOne passive output ports for DP1.2 at 5.4Gbps ÎÎOne active output port with integrated DP to HDMI re- driver (level shifter) supports HDMI 1.4 at 3.4Gbps ÎÎPin control mode supports auto port priority selection ÎÎPin control mode supports port2 with DDC bi-direction buffer switch only ÎÎI2C control mode supports auto port priority selection ÎÎI2C control mode supports port2 with 8 levels equalization and 5 levels pre-emphasis ÎÎI2C control mode supports port2 with either DDC bi- direction buffer switch or DDC passive switch ÎÎVery low operating power when passive port1 is selected ÎÎ3.3V power supply ÎÎ2KV HBM ESD protection for all I/O pins of port1 and all control pins ÎÎ8kV contact ESD (IEC61000-4-2) protection for all output pins in port2 ÎÎPackaging: 60 pin TQFN package (5x9mm, 0.4mm pitch) ÎÎSupport Type 2 cable ID register Description PI3WVR31212A has one passive output port1, one active (DP to HDMI) output port2. Passive output supports DP1.2 at 5.4Gbps in I2C mode. Active port2 supports HDMI1.4b at 3.4Gbps.All two output ports support auto port priority selection. Input port accepts DP1.2 and DP++ signals associated with output ports as described above.
