XR22414CV48TR-F

Overview

The XR22414CV48TR-F is a USB 2.0 compliant hub controller manufactured by MaxLinear, Inc., designed for high-speed data transfer applications. It features four downstream ports and supports Full Speed (12 Mb/s) and High Speed (480 Mb/s) data rates, with an upstream connection capability at 1.5 Mb/s. The device operates within a voltage range of 3 V to 3.6 V for the core logic and 4.4 V to 5.5 V for I/O interfaces, consuming approximately 42 mA of operating current. Packaged in a QFN-48 surface-mount format, it functions reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Supports USB 2.0 specifications including Multi-TT capabilities for efficient bandwidth management on bulk and interrupt transfers.

Applications

• Connecting multiple USB peripherals to a single host port in computing systems.
• Expanding connectivity in industrial control panels requiring robust interface solutions.
• Integrating into consumer electronics devices needing additional downstream USB access points.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential supply chain variations. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions account for moisture sensitivity levels specified in the package documentation to prevent damage during soldering processes.

Selection Notes

Select this model when a compact, low-power USB hub solution is required for space-constrained designs. Consider the QFN-48 package for thermal performance and board real estate efficiency. Validate that the system power supply meets the distinct voltage requirements for core and I/O domains to ensure stable operation under varying load conditions.

Part Context

This component belongs to the XR22414 series of USB hub controllers, which are engineered for versatile connectivity needs. It serves as a bridge between host controllers and peripheral devices, facilitating data exchange in environments where standard USB ports are insufficient. The series emphasizes reliability and compliance with industry standards for seamless interoperability.
