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.
