the isolating, I am planing to use the ADuM3160BRWZ.
But now I am completely confused about the USB speed and compatibility.
The datasheets states the following:
- USB 2.0 compatible
- Low and full speed data rate: 1.5Mpbs and 12Mbps
So isn't USB2.0 actually called Hi-Speed and provides 480Mps?
Where am I wrong?
USB2.0 supports Low, Full and High speed. However you do not have to support
High speed to be USB2.0 compliant. You just need to handle the request
properly, on other words reject the high speed chirp with grace.
Our part meets the requirements to work in USB2.0 systems, while supporting Low
(1.5Mbps) and Full (12Mbps) speed data transfers. We are working on 480Mbps,
but we are looking at a year out.
