PI3DPX1225ZLBEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1225ZLBEX is a USB Type-C DP-Alt DP 2.1 UHBR13.5/USB 3.2 Gen 2 6:4 Linear ReDriver supporting DP Link-Training Transparent for Source-side applications. It complies with VESA DP Alt 2.1 UHBR13.5 and USB 3.2 Gen 2 standards. The device features adjustable equalization, output swing, and gain values via I2C control to optimize signal performance over various physical mediums by reducing inter-symbol interference jitters. It utilizes a non-blocking linear architecture that provides better additive jitter performance than conventional CMOS limiting redrivers. The component operates on a single 3.3V power supply and supports slave I2C mode speeds up to 1MHz.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'E' confirms lead-free and green status, and 'X' indicates tape and reel packaging. Confirm compliance with EU RoHS directives (2002/95/EC, 2011/65/EU, 2015/863/EU) and halogen/antimony-free requirements if specified for your project. Ensure the W-QFN6040-40 package dimensions match your PCB footprint design constraints.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component for source-side applications requiring transparent DisplayPort link training without dependency on DP-Aux channels. Choose the linear redriver architecture over limiting types when lower additive jitter is critical. Ensure the system supports I2C configuration for adjusting equalization and gain settings to match the specific physical medium characteristics.
