TUSB2046BVF (TEXAS INSTRUMENTS)
USB интерфейс, Контроллер USB Концентратора, USB 2.0, 3 В, 3.6 В, LQFP, 32 вывод(-ов)
The TUSB2046BVF is a 4-port Full-Speed Universal Serial Bus Hub that provides one upstream port and four downstream ports in compliance with the Universal Serial Bus (USB) specification as a full-speed hub. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports. The downstream ports support full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The configuration of the BUSPWR pin selects either the bus-powered or the self-powered mode. The TUSB2046B provides the flexibility of using a 6 or a 48MHz clock. The logic level of the TSTMODE terminal controls the selection of the clock source.
