PTN3222GMJ

Signal Buffers, Repeaters, Splitters Overview

The PTN3222GMJ is a single-port eUSB2 to USB2 redriver IC manufactured by NXP Semiconductors. It translates between eUSB2 and USB2 signaling schemes, supporting host repeater, device repeater, and dual-role repeater functions. The component operates at Low Speed (1.5 Mbps), Full Speed (12 Mbps), and High Speed (480 Mbps). It utilizes two power supplies: VDD3V3 and VDD1V8. The device is housed in an XQFN12 package with dimensions of 1.75 mm x 2.2 mm and a 0.4 mm pitch. It supports I2C target interface for configuration and includes robustness features such as over-voltage protection on data pins.

Signal Buffers, Repeaters, Splitters Feature Summary

• Performs translation between eUSB2 and USB2 signaling schemes
• Supports host, device, and dual-role repeater functionality
• Configurable signal integrity parameters for both eUSB2 and USB2 ends
• Integrated over-voltage protection on USB2 data pins

Signal Buffers, Repeaters, Splitters Applications

• eUSB2 to USB2 repeater function in host platforms
• eUSB2 to USB2 repeater function in peripheral devices
• Protocol bridges connecting eUSB2 controllers to standard USB connectors

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering part number PTN3222GMJ against the required XQFN12 package type. Confirm that the application design accommodates the dual power supply requirements of VDD3V3 and VDD1V8. Ensure the PCB layout adheres to the specified ground plane connections for AGND and DGND to maintain signal integrity and minimize noise.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the PTN3222GMJ when a QFN12 footprint is preferred over the WLCSP12 option. This package variant is suitable for applications requiring thermal enhancement capabilities provided by the plastic thermal enhanced thin quad flat package. Verify compatibility with the system's I2C address selection strategy using the quaternary ADDR pin.

Signal Buffers, Repeaters, Splitters Part Context

The PTN3222GMJ belongs to the PTN3222 family of 1-port eUSB2 to USB2 redrivers. It shares core functional specifications with other variants like the PTN3222CUK but differs in physical packaging. The family is designed to enable advanced SoCs to interface with traditional USB2 applications over long PCB traces while maintaining signal quality.

Signal Buffers, Repeaters, Splitters Replacement Considerations

PTN3222CUK serves as a package alternative within the same family, utilizing a WLCSP12 form factor instead of the XQFN12.
