PI3HDX612ZLDEX

Signal Buffers, Repeaters, Splitters Overview

The PI3HDX612ZLDEX is a 6Gbps HDMI 2.0 active signal duplicator manufactured by Diodes Incorporated in a 40-pin TQFN (W-QFN3060-40) package. It supports data rates up to 6Gbps for 4K@60Hz resolution and operates on a single 3.3V power supply with a voltage range of 3.0V to 3.6V. The device features quad-level equalizer gain, flat gain, and output swing linearity selection via pin straps or I2C programming. It includes CTLE equalizers at the inputs to reduce ISI jitter and compensate channel loss, ensuring high-bandwidth video stream transmission from sources to multiple display units.
