ISOLATED USB

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 to12Mbit/s. Figure 5 shows a

circuit diagram of the implementation of the ADuM3160 on the

ez

LINX hardware.

power 5. 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.
