The PI3HDX612 active-drive Signal Duplicator solution is targeted for high-resolution video networks that are based on HDMI™ 2.0 standards signal processing.

The PI3HDX612 is an active single-channel to two-channel Signal Duplicator. The device drives differential signals to multiple video display units. Depending on the mode select pin, the PI3HDX612 provides controllable equalizer, flat gain and output swing linearity that can be manipulated through pin control or I2C control.

The maximum HDMI™ data rate of 6Gbps produces a 4K@60Hz resolution or 2K@144Hz, required for 4K HDTV, PC graphics products and other peripheral device. For PC graphics application, the device sits at the driver’s side and fans out differential signals to multiple display units including PC LCD monitors, projectors, and TVs. The CTLE equalizers are implemented at the inputs of the ReDriver to reduce the ISI jitters and compensate channel loss. The PI3HDX612 ensures the transmittal of high bandwidth video streams from video sources to the end-display units.
