CMOS and monolithic air core transformer technology, this
isolation component provides outstanding performance
characteristics and is easily integrated with low and full speed
USB-compatible peripheral devices.
Many microcontrollers implement USB so that it presents only
the D+ and D− lines to external pins. This is desirable in many
cases because it minimizes external components and simplifies
the design; however, this presents particular challenges when
isolation is required. Because the USB lines must switch
between actively driving D+/D− and allowing external resistors
to set the state of the bus, the ADuM3160 provides mechanisms
for detecting the direction of data flow and control over the
state of the output buffers. Data direction is determined on a
packet-by-packet basis.
The ADuM3160 uses the edge detection based iCoupler
technology in conjunction with internal logic to implement a
transparent, easily configured, upstream-facing port isolator.
Isolating the upstream port provides several advantages in
simplicity, power management, and robust operation.
The isolator has a propagation delay comparable to that of a
standard hub and cable. It operates with the bus voltage on
either side ranging from 4.5 V to 5.5 V, allowing connection
directly to V
signaling level. The ADuM3160 provides isolated control of the
pull-up resistor to allow the peripheral to control connection
timing. The device draws low enough idle current that a suspend
state is not required. A 5 kV version, the ADuM4160, is also
available.

... Hubs can be isolated like any other peripheral. Isolated hubs can be created by placing an ADuM3160 on the upstream port of a hub chip. This configuration can be made compliant if counted as two hub delays. The hub chip allows the ADuM3160 to operate at full speed yet maintains compatibility with low speed devices ...

... Because the ADuM3160 sets its speed by hardwiring pins, the part cannot adjust to different peripherals on the fly. The practical result of using the ADuM3160 in a host port is that the port works at a single speed. This behavior is acceptable in embedded host applications; however, this type of interface is not fully compliant as a general-purpose USB port ...
