ezLINX™ Isolated USB Implementation

Hardware Implementation

The Isolated USB port is implemented using the ADuM3160 Full speed USB Isolator. The ADuM3160 connects to the integrated USB PHY of the ADSP-BF548 and is capable of functioning at data rates of up to 12Mbit/s. Figure 1 below shows a circuit diagram of the implementation of the ADuM3160 on the ezLINX hardware.

Figure 1.

The VBUS1 and VDD1 of the ADuM3160 is powered from the 5V bus power supply. VBUS2 and VDD2 is powered from 3.3V generated by the ezLINX power supply. A mini USB-B connector is used for easy connection to a USB master.
