TUSB2036 Datasheet

Integrated USB Transceivers


The TUSB2036 hub is a 3.3-V CMOS device that provides up to three downstream ports in compliance with the USB 2.0 specification. 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 both 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 terminal selects either the bus-powered or the self-powered mode. Theintroduction of the DP0 pullup resistor disable terminal, DP0PUR, makes it much easier to implement an on-board bus/self-power dynamic-switching circuitry. With the new function terminal, the end-equipment vendor can reduce the total board cost while adding additional product value.
