PI3DPX1207BZHE

Signal Buffers, Repeaters, Splitters Overview

The PI3DPX1207BZHE is a DisplayPort Alt Mode 1.4 linear redriver manufactured by Diodes Incorporated, designed for USB 3.1 Gen 2 and DP-Alt applications with a maximum data rate of 10 Gbps per channel. It features four differential channels (two for DisplayPort and two for USB) housed in a 42-pin TQFN package measuring 3.5x9 mm. The device operates on a single 3.3V power supply within a voltage range of 3.0V to 3.6V. It supports adjustable equalization, flat gain, and output swing settings via pin strapping or I2C control up to 1MHz. The component functions as a non-blocking, latency-free linear redriver that natively supports DisplayPort transparent link training without auxiliary channel dependency.

Signal Buffers, Repeaters, Splitters Feature Summary

• Non-blocking linear redriver design enabling native support for DisplayPort transparent link training independent of the DP-Aux listener.
• Trace Loss Canceling technology allowing seamless cascading of multiple units to compensate for high insertion loss in host-to-device links.
• Flexible mode switching between USB 3.1 Gen 2 and DisplayPort 1.4 configurations with built-in Type-C plug/unplug and flipping orientation controls.
• Independent signal output adjustment capabilities for equalization, gain, and swing across DisplayPort and USB modes.

Signal Buffers, Repeaters, Splitters Applications

• Notebook, desktop, and all-in-one personal computers
• Active DisplayPort Alt Mode cables and adapters
• DisplayPort Alt Mode monitors and displays

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging details. The ZHE designation indicates a lead-free, green product compliant with RoHS directives, supplied in tape and reel format. Confirm current availability status as manufacturing lifecycles may change, and ensure the selected variant matches the required operational temperature range and interface specifications for the target system.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when designing systems requiring latency-free signal regeneration for high-speed differential pairs. Ensure the PCB layout accommodates the 42-pin TQFN footprint and provides adequate thermal dissipation through the exposed pad. Verify that the host controller can support the required I2C addressing or that pin-strapping configurations align with the desired channel mapping and equalization presets.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PI3DPX1207 family of DisplayPort Alt Mode redrivers from Diodes Incorporated. It serves as a specialized interface solution for managing signal integrity in Type-C connectors where both USB and DisplayPort signals share the same physical lanes. The device complements other family members like the PI3DPX1205A, which functions as an active mux rather than a pure redriver.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PI3DPX1207B is functionally similar to the PI3DPX1207Q series, though package and temperature variations may exist. Direct pin-compatible replacements within the same family should be verified against the official datasheet comparison tables to ensure identical electrical characteristics and control logic compatibility.
