| Looking for (Optically) isolated data transmission at 500+MBits over ~60cm |
| << < (2/2) |
| Ysjoelfir:
That would be possible in theory, but the problems are: - Size! - We would need to re-engineer the whole communication system - we would need several cards, as the device can have several channels, each needing its own (two) communication interfaces - I guess that would be pretty expensive as well. |

Did you read this paper: https://www.cleverscope.com/files/The%20Cleverscope%20CS448%20Development%20Journey.pdf ? |
| Ysjoelfir:
I have not but I will read it now as it looks very promissing :) |

A couple news releases is all that's on the web. Too good to be allowed to be sold for appropriate prices to plebians? When you look at normal 10+ gbps stuff they want to absolutely rape your wallet, I don't think cleverscope paid those kinds of prices. |

If they don't like inductive isolation, how about capacitive? There are digital isolator ICs such as the Si86xx series, with up to 6 channels across up to 5kV in a wide SOIC-16, but they're too slow unless you have a bit of room on the board to (de)mux the data stream over multiple lanes. |
