PI3DPX1207BZHEX

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1207BZHEX is a DP-Alt 1.4 and USB 3.1 Gen 2 linear redriver manufactured by Diodes Incorporated. It supports data rates up to 10 Gbps across four channels, comprising two DisplayPort lanes and two USB lanes. The device operates on a single 3.3V power supply within a voltage range of 3.0V to 3.6V. It utilizes a 42-pin TQFN package measuring 3.5x9mm. The component features non-blocking latency-free operation, supporting transparent DisplayPort link training without auxiliary channel dependency.

Signal Buffers, Repeaters, Splitters Feature Summary

• Non-blocking linear redriver design enabling transparent DisplayPort link training
• Supports Type-C plug/unplug detection and flipping orientation control
• Adjustable equalization, flat gain, and output swing via pin or I2C settings
• Built-in auto power saving circuit for low standby power consumption

Signal Buffers, Repeaters, Splitters Applications

• Notebook, desktop, and AIO personal computers
• DP-Alt monitors and displays
• Active DP-Alt cables and adapters

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix 'ZHEX' corresponds to the tape and reel packaging format as defined in the manufacturer's documentation. Confirm that the component meets RoHS 3 compliance standards required for your assembly process. Ensure the I2C address pins are configured correctly for your system topology to avoid bus conflicts.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring high-speed signal integrity for DisplayPort Alt Mode and USB 3.1 Gen 2 interfaces. The linear architecture is suitable for applications needing low additive jitter and support for cascaded connections. Verify that the host controller can manage the I2C configuration registers if dynamic mode switching is required.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3DPX1207 family of DP-Alt redrivers from Diodes Incorporated. It is distinct from limiting-type redrivers like the PI3DPX1202A due to its linear signal processing approach. The ZHEX suffix indicates the specific 42-pin TQFN package with tape and reel shipping configuration.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI3DPX1207B is functionally similar to the PI3DPX1205A but differs in package type (42-pin vs 40-pin) and control interface flexibility. Direct pin-to-pin replacement is not possible due to the different pin counts and package dimensions.
