PI3HDX412BDZBE

PI3HDX412BDZBE is a DMI 1.4b 1:2 splitter/demux for 3.4Gbps data rate with equalization and pre-emphasis. It is an active-drive switch solution targeted for high-resolution video networks that are based on HDMITM/DVI standards and TMDS signal processing. It is an active single TMDS channel to a two TMDS channel splitter and DeMux with Hi-Z outputs. The device drives differential signals to multiple video display units. Depending on the mode select pin, the PI3HDX412BD provides controllable output swing levels that can be manipulated through pin control or I2C control. This solution also provides a unique and advanced pre-emphasis technique to increase rise and fall times. It ensures the transmittal of high-bandwidth video streams from PC graphics sources to the end-display units. It also provides enhanced and robust ESD/EOS protection, which is required by many consumer video networks today. Applications include display peripheral box, digital signage display, video processing device.
