Supports both AC-coupled and DC-coupled inputs The PI3HDMI412AD is an active single TMDS channel to two 1:2 Demux TMDS channel DeMux with Hi-Z outputs. The device drives TM Supports Deep Color Signals differential signals to multiple video display units. It provides three controllable output swing levels that can be controlled through Con gurable output swing control (500mV, 750mV, 1000mV) 2 pin control or I C control, depending on the mode select pin. The Con gurable Pre-Emphasis levels (0dB, 1.5dB, 3.5dB, 6.0dB) swing levels are 500mV, 700mV & 1000mV. This solution also Con gurable De-Emphasis (0dB, -1.5dB, -3.5dB, -6.0dB) provides a unique advanced pre-emphasis technique to increase Con gurable Equalization (1dB,3.5dB, 6dB, 8dB) rise and fall times which are reduced during transmission across Data Rate = 2.5Gbps (Max) long distances. Inputs w/ built-in termination TM The maximum DVI/HDMI data rate of 1.65Gbps provides a Propagation delay < 2ns input 1920x1080 resolution required by the next Gen HDTV and PC Uni-Directional graphics products. Due to its active uni-directional feature, this switch is de-signed for usage only for the video drivers side. For 10kV HBM ESD protection on all high speed data channels PC graphics application, the device sits at the drivers side to (Supplemental contact ESD test results are available upon switch between multiple display units, such as PC LCD monitor, request) projector, TV, etc. Packaging (Pb-free & Green): 56-pad TQFN (ZB56) TM PI3HDMI412AD is the industrys rst active DVI/HDMI compliant switch, which ensures transmitting high bandwidth video streams from PC graphics source to end display units. PI3HDMI412AD will also provide enhanced robust ESD/EOS protection, which is required by many consumer video networks today.
