Four Port SuperSpeed USB 5Gbps USB3.0 Hub

The TUSB8040A is a four-port USB 3.0 compliant hub and is available in a 100-pin QFN package. The device is designed for operation over the commercial temperature range of 0°C to 70°C.

The TUSB8040A provides simultaneous SuperSpeed USB and high-speed or full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed, full-speed or low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed or low-speed connections, SuperSpeed USB and high-speed connectivity are disabled on the downstream ports.

The TUSB8040A supports up to four downstream ports. It may be configured to report one to four downstream ports by pin selection or by an attached EEPROM or SMBus controller. The configuration options provide the ability to scale the device by application.
