Universal Serial Bus (USB) Cable Isolator Circuit Download White Paper 600Ko

The universal serial bus (USB) is rapidly becoming the standard interface for most PC peripherals due to superior speed flexibility and support of device hot swap. However, there is concern over how to provide the isolation required for connections to machines that control dangerous voltages. The ADuM4160 is designed primarily as an isolation element for a peripheral USB device; though there are occasions when it is useful to create an isolated cable function. This circuit isolates a peripheral device that already implements a USB interface. It will provide a convenient isolated USB cable solution that provides power to the peripheral as well as operation at a fixed speed.

The development platform for i.MX 6Quad from element14 (built to the Freescale SABRE Lite design) is an evaluation platform featuring the powerful i.MX 6Q, a multimedia application processor with Quad ARM Cortex-A9 cores at 1.2 GHz from Freescale Semiconductor.

This month, Freescale and element14 are giving away five such platforms, worth £128.06 each, for EETimes Europe's readers to win. The platform helps evaluate the rich set of peripherals and includes a 10/100/Gb Ethernet port, SATA-II, HDMI v1.4, LVDS, parallel RGB interface, touch screen interface, analog headphone/microphone, micro TF and SD card interface, USB, serial port, JTAG, camera interface, and input keys for Android. 


 

And the winners are...

In our previous reader offer, Pico Technology was giving away one of its recently launched PicoScope 3207B, a 2-channel USB 3.0 oscilloscope worth 1451 Euros. Lucky winner Mr L. Sanchez-Gonzalez from Spain should be receiving his PicoScope 3207B soon. Let's wish them some interesting findings with his projects.
