To support multiple ports a single USB3300 host can be combined with one of SMSC’s many hub
products to expand the number of ports. SMSC has 2-port, 3-port, 4-port, and 7-port hub designs which
can be used to expand the number of ports in a design.
Using a SMSC hub to expand the number of ports allows a single Link to run several USB devices
without a separate Link to support each USB port. Another advantage of using a SMSC hub is on
products where the main board is not located near the USB ports. The USB3300 can be placed on
the main board with the Link ASIC and the hub can be placed on a separate board next to the USB
ports. The only data connection required between the boards is DP and DM.
The CPEN output of the USB3300 is optional and can be used to turn the Hub on or off to lower current
when the USB connection isn’t needed.
An evaluation board, EVB-USB3300, is available for building a prototype system with the USB3300.
The evaluation board provides an industry standard T&MT connector to interface a ULPI Link controller
and a Mini-AB connector for the USB cable. A 500mA fault protected 5V Vbus switch that is controlled
by the USB3300 is also included.
