The DB525U2H403F-3 is a high-performance Universal Serial Bus (USB) 2.0 Hub.

DB525U2H403F-3 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 DB525U2H403F-3 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.

• Compliant with USB 2.0 (Data Rate 1.5/12/480Mbps)
• 4 (max.) downstream facing ports. (Three External USB A receptacle connectors + One Internal Intel block standard single USB port)
• 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
• ESD protection up to 4 KV on all USB pins.
• Upstream port (Right angle USB B receptacle connector)
• Self-powered operation.
• DC power input: Floppy drive like mini-4pin power connector (Min. DC +5V/2.5A)
• USB Bus Power
  • P1 and P4 (Support the USB Battery Charging specification)
    USB Battery Charging is supported on downstream USB Port 1 and Port 4 to a full 1.5A .
  • P2 and P3
    P2 and P3 will be able to supply USB bus power totally 1A.
    For Example: P2 = 700mA, P3 = 300mA
• Supports Over-current detection and Individual power control.
• Customizable vendor ID, product ID, and device ID.
• Provides downstream ports Bus-Power statusLEDs (Green)
