XR22404CG28TR-F

Overview

The XR22404CG28TR-F is a USB 2.0 multi-port hub controller manufactured by MaxLinear, Inc., designed for high-speed data transfer applications. It supports four downstream ports and integrates a Multi-Transaction Translator (MTT) to manage bandwidth efficiently across connected devices. The component operates within a supply 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, ensuring compatibility with standard USB power specifications. It features a maximum operating current of 42 mA and supports data rates up to 480 Mb/s for High Speed mode, alongside Full Speed at 12 Mb/s and Low Speed at 1.5 Mb/s. The device is housed in a QFN-48 surface-mount package suitable for compact electronic designs.

Feature Summary

• Integrates a Multi-Transaction Translator (MTT) to optimize bandwidth allocation for multiple downstream devices.
• Supports USB 2.0 High Speed operation with backward compatibility for Full and Low Speed peripherals.
• Features dual-voltage operation to accommodate both low-power core logic and standard USB I/O requirements.

Applications

• USB expansion hubs for consumer electronics and industrial equipment
• Embedded systems requiring multiple peripheral connections via a single upstream link
• Data acquisition systems utilizing multiple USB-connected sensors or instruments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Confirm availability status as distribution channels may list discontinued or limited-stock items. Ensure compliance with RoHS directives if required for the target market. Cross-reference the Mouser part number 701-XR22404CG28TR-F with the original manufacturer documentation to validate authenticity and revision level before procurement.

Selection Notes

Select this component when a compact solution for connecting multiple USB peripherals is required without external host overhead. The integrated MTT makes it suitable for scenarios involving mixed-speed devices. Ensure the design accommodates the dual voltage domains (3.3V/5V) and the QFN-48 thermal pad requirements for adequate heat dissipation during continuous high-speed data transfers.
