The U2H403SV is a high-performance Universal Serial Bus (USB) 2.0 Hub.

U2H403SV 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 U2H403SV 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. (Straight 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
• 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
    The USB bus power of P1 and P4 USB downstream ports were
    protected by 750mA PTC Resettable Fuse.
  • 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.
