PTN3222CUKZ

Signal Buffers, Repeaters, Splitters Overview

The PTN3222CUKZ 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, or 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. Powered by VDD3V3 and VDD1V8 supplies within a 1.62 V to 3.63 V range, it operates from -40 °C to +85 °C. The component is housed in a WLCSP-12 package with dimensions of 1.55 mm x 1.18 mm x 0.455 mm.

Signal Buffers, Repeaters, Splitters Feature Summary

• Performs translation between eUSB2 and USB2 signaling schemes for host, device, or dual-role applications.
• Configurable signal integrity parameters including Tx de-emphasis, Rx equalization, and output swing on both interfaces.
• Supports BC1.2 power provider CDP configuration capability in host mode via I2C control.
• Features robust protection including over-voltage tolerance on USB2 data pins and backpower safety.

Signal Buffers, Repeaters, Splitters Applications

• eUSB2 to USB2 repeater function in platforms such as hosts, devices, hubs, routers, and protocol bridges.
• Systems utilizing Standard A, Standard B, Micro-B, or USB Type-C connector scenarios.
• Direct interface connections between application processors with eUSB2 PHY and USB2 peripheral connectors.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix Z indicates the standard reel packaging format when sourcing this component. Confirm that the WLCSP12 package variant matches the required PCB footprint dimensions of 1.55 mm by 1.18 mm. Ensure the design supports the dual power supply requirement of VDD3V3 and VDD1V8 for proper operation across the specified temperature range.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the PTN3222CUKZ when a small form factor is required, as it utilizes the WLCSP12 package compared to the larger QFN12 option. This part is suitable for designs needing configurable signal integrity adjustments and support for all USB2 data rates. Verify that the system can accommodate the quaternary I2C address selection via the ADDR pin if multiple devices are present.

Signal Buffers, Repeaters, Splitters Part Context

The PTN3222CUKZ belongs to the PTN3222 series of interface integrated circuits designed by NXP Semiconductors. It serves as a specialized redriver to bridge legacy USB2 connectivity with modern eUSB2 interfaces found in advanced SoCs. The series includes variants like the PTN3222GM in a QFN12 package, offering flexibility in package selection based on thermal and spatial constraints.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PTN3222GM is a direct functional alternative within the same family, differing primarily in package type (QFN12 vs. WLCSP12). When substituting, verify that the PCB layout accommodates the different pin pitch and physical dimensions of the QFN12 package while maintaining identical electrical performance.
