Analog Devices ADuM4160 USB Digital Isolator

Analog Devices ADuM4160 USB Digital Isolator is a USB port isolator based on iCoupler® technology. ADI ADuM4160 combines high speed CMOS and monolithic air core transformer technology to provide outstanding performance characteristics. The device is easily integrated with low and full speed USB-compatible peripheral devices. ADuM4160 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. ADI ADuM4160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream facing port isolator. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation. The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the supply voltage on either side ranging from 3.1 V to 5.5 V, allowing connection directly to VBUS by internally regulating the voltage to the signaling level. ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing.
