The U2H403F is a high-performance Universal Serial Bus (USB) 2.0 Hub.

U2H403F 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 U2H403F 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. (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
• 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
    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 status LEDs (Green)

• 25 (H) x 101.6 (W) x 90 (D) mm
• Form Factor
  • 3.5" FDD Form Factor
