ISOLATED USB
The isolated USB port is implemented using the ADuM3160 full
speed USB isolator. The ADuM3160 connects to the integrated
PHY of the ADSP-BF548’s USB controller and is capable of fun-
ctioning at data rates of up to12 Mbit/sec. Figure 5 shows a circuit
diagram of the implementation of the ADuM3160 on the ezLINX
hardware.
Hardware User Guide
The VBUS1 pin (Pin 1) and VDD1 pin (Pin 3) of the ADuM3160 are
powered from the 5 V VBUS line of the USB mini connector and
can only be connected to a USB master. The VBUS2 pin (Pin 16)
and VDD2 pin (Pin 14) are powered from the 3.3 V generated by
the ezLINX power supply.
