U2H4+ATA11S is an USB 2.0 four-port HUB with one USB to IDE (ATA/ATAPI) bridge. U2H4+ATA11S provides three downstream USB ports, one IDE (ATA/ATAPI) port. It is ideally suited for docking station solution which need more USB port and interface for connecting two ATA devices.

It allows ATA drives (Master and Slave) to be connected to USB 2.0 serial bus in a plug-and-play fashion.

U2H4+ATA11S combines two key components:
1). Four ports USB 2.0 High Speed Hub
2). USB 2.0 to IDE(ATA/ATAPI) Bridge Controller

1). Four ports USB 2.0 High Speed Hub:

U2H4+ATA11S provides high-performance four downstream USB ports.
U2H4+ATA11S 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 U2H4+ATA11S 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 downstream ports
  • Two downstream ports (USB1&2) are Intel block berg-strip header (2x5/9 pin).
  • One downstream port (USB3) is Intel block berg-strip header (2x5/9 pin).
  • One downstream internal port for USB 2.0 to ATA/SATA Bridge Board
• Upstream port
  • USB B-Type connector
• Multiple transaction translator (MTT)
  • One TT per downstream port for maximum performance
• All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) transaction.
