PTN36502AHQX

Signal Buffers, Repeaters, Splitters Overview

The PTN36502AHQX is a Type-C USB 3.1 Gen 1 and DisplayPort v1.2 combo redriver designed to extend signal reach for high-speed differential data flows in both Downstream Facing Port (DFP) and Upstream Facing Port (UFP) applications. It supports USB 3.1 Gen 1 at 5 Gbps and DisplayPort rates up to 5.4 Gbps (HBR2). The device operates from a single 1.8 V supply and features an extremely thin HX2QFN24 package measuring 2.4 mm x 3.2 mm x 0.35 mm with a 0.4 mm pitch. Configuration is achieved via ternary GPIO pins or an I2C interface operating up to 1 MHz.

Signal Buffers, Repeaters, Splitters Feature Summary

• Supports flexible signaling combinations including USB 3.1 Gen 1 only, combined USB/DP modes, and full 4-lane DisplayPort operation.
• Integrates receive equalizers and active transmit de-emphasis to compensate for signal attenuation in PCB and cable channels.
• Includes a built-in AUX crossbar switch that automatically adjusts polarity to support reversible plug orientation.
• Features autonomous power management that dynamically activates or deactivates internal circuitry based on link electrical conditions.

Signal Buffers, Repeaters, Splitters Applications

• USB Type-C Host/Source devices such as smartphones, tablets, notebooks, and desktop computers
• Hub or Dock Devices requiring high-speed signal extension
• USB Type-C Device/Sink applications including docking stations and display units

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering part number PTN36502AHQX against the manufacturer's current product status. Confirm that the HX2QFN24 package dimensions and pinout align with your PCB layout requirements. Ensure the design accommodates the required 1.8 V supply voltage and appropriate pull-up resistors for the I2C control interface if utilized.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when a platform requires simultaneous support for USB 3.1 Gen 1 and DisplayPort Alt Mode signals within a compact form factor. It is suitable for designs needing configurable signal conditioning via either hardware pins or software-controlled I2C registers. Consider its low-power states for battery-operated mobile applications requiring efficient power management during idle or low-power USB modes.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to NXP's Type-C USB 3.1 Gen 1 and DisplayPort v1.2 combo redriver family. It shares functional similarities with other redrivers but is distinct in its ability to handle four high-speed differential data flows simultaneously. The 'A' suffix in the model number indicates a specific I2C address configuration compared to the standard PTN36502 variant.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PTN36502HQ serves as a direct alternative with a different I2C address. Verify compatibility by checking the 7-bit I2C address settings; PTN36502 uses 001 1010 while PTN36502A uses 001 0010. Ensure any replacement maintains the same HX2QFN24 package footprint and 1.8 V supply requirement.
