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.
The USB3300 is protected from ESD strikes. By eliminating the requirement for external ESD
protection devices, board space is conserved, and the board manufacturer is enabled to reduce cost.
The advanced ESD structures integrated into the USB3300 protect the device whether or not it is
powered up.
Human Body Model (HBM) Performance
HBM testing verifies the ability to withstand the ESD strikes like those that occur during handling and
manufacturing, and is done without power applied to the IC. To pass the test, the device must have
no change in operation or performance due to the event. All pins on the USB3300 provide
protection.
