Introduction

The DB525U2H402 is a high-performance Universal Serial Bus (USB) 2.0 Hub.

DB525U2H402 is designed with Multiple Transaction Translator (MTT) USB 2.0 HUB controller.

Multiple Transaction Translator (MTT) provides individual TT control logics for each downstream port. This is a performance better choice for USB 2.0 Hub

The DB525U2H402 works backward compatible either when any one of downstream ports are connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host.
    Technical Specifications
    • Compliant with USB 2.0 (Data Rate 1.5/12/480Mbps)
    • 4 (max.) downstream facing ports. (Right angle USB A receptacle connector)
    • All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) transaction.
    • Multiple transaction translator (MTT)
      • One TT per downstream port for maximum performance
    • Supports split transaction to handle full-speed and low-speed on downstream facing ports when Hub controller is working in high-speed mode.
    • Upstream port (Right angle USB B receptacle connector)
    • Supports self-powered mode.
    • DC Power Connector: Walkman-type 2.0 mm DC Jack
      • Power Input Range: DC 5V/2.5A
    • Supports Over-current detection and Individual power control
    • Supports Energy Star for PC peripheral system.
    • Supports downstream ports status with LEDs (Amber and Green)
