PTN3222DUKZ

Signal Buffers, Repeaters, Splitters Overview

The PTN3222DUKZ is a single-port eUSB2 to USB2 redriver manufactured by NXP Semiconductors. It translates between eUSB2 and USB2 signaling schemes, supporting host repeater, device repeater, and dual role repeater functions. The IC conforms to USB2 specifications and eUSB2 specification v1.1, handling Low Speed (1.5 Mbps), Full Speed (12 Mbps), and High Speed (480 Mbps) data rates. It operates on dual power supplies: VDD3V3 and VDD1V8. The component is housed in a WLCSP12 package with dimensions of 1.55 mm x 1.18 mm x 0.455 mm and a 0.35 mm pitch. It supports an I2C target interface for configuration and features robust protection including 5.5 V tolerance on USB2 data pins.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the ordering part number PTN3222DUKZ against the type number PTN3222DUK in official documentation. Confirm the WLCSP12 package details and temperature range requirements match the application environment. Ensure I2C address selection via the ADDR pin aligns with system bus constraints. Check for specific decoupling capacitor placement guidelines near power pins during integration.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when interfacing eUSB2 PHYs with standard USB2 connectors or cables. Consider the WLCSP12 package size for space-constrained designs. Verify that the system can provide both 3.3V and 1.8V power rails. Evaluate the need for I2C configuration versus default POR settings based on platform complexity. Ensure ESD protection strategies complement the internal 2 kV HBM rating.

Signal Buffers, Repeaters, Splitters Part Context

The PTN3222DUKZ belongs to the PTN3222 series of 1-port eUSB2 to USB2 redrivers from NXP Semiconductors. This series addresses the need for signal integrity preservation when bridging eUSB2 interfaces on advanced SoCs with traditional USB2 peripherals. It serves as a critical interface solution in modern computing and mobile platforms where form factor reduction requires eUSB2 adoption while maintaining compatibility with standard USB2 ecosystems.
