Product Description

The PI3HDX414, active-drive switch solution is targeted for high-resolution video networks that are based on HDMI/DVI standards, and TMDS signal processing.

The PI3HDX414 is an active single TMDS channel to four TMDS channel Splitter and DeMux with Hi-Z outputs. The device drives differential signals to four video display units. It provides controllable output swing levels that can be controlled through pin control or I2C control, depending on the mode select pin. This solution also provides a unique advanced pre-emphasis technique to increase rise and fall times.

The maximum HDMI/DVI data rate of 3.4Gbps provides a 1920x1080 @60Hz resolution or 4K @30Hz required for 4K HDTV and PC graphics products. For PC graphics application, the device sits at the driver’s side to switch between multiple display units, such as PC LCD monitor, projector, TV, etc.

The PI3HDX414 ensures transmitting high bandwidth video streams from PC graphics source to end display units. It will also provide enhanced robust ESD/EOS protection, which is required by many consumer video networks today.
