The first man in the world that talking slower than u ;) Good Video!
This is probably the best place on youtube to learn hardware design. The quality of the content is just phenomenal.
It's really humbling to see a discussion on such advanced topics :) Thanks Robert, learned a lot
MIPI is also used to control RF Power amplifiers in our smart phones
Struggled with the mic setup on this one. Kinda hard to follow along. Still, interesting info and the links to papers in the presentation were helpful.
I understand that information on an optical fiber is transmitted through various frequencies of light and must accommodate the time skew of the different wavelengths of light and demultiplexed by a prism for example.
I have done a video on optical chips, may be interesting and explain a little bit more: ruclips.net/video/65FS0sxQz3I/видео.html
Really fascinating. Thank you.
Another awesome video Robert, you're on a roll!
Awesome Robert. I expect more on this. I've learnt complete Altium from your videos only.
Great video. Is the PowerPoint presentation available?
Here's a suggestion Robert, create a series of videos on CubeSat development
I don't watch it yet but looking forward to it =)
Good information video .
I think there is much beyond this high speed interfaces to know.
Try to do more interactive videos.
I have a question. What are the differences between PCIe PHYs and Ethernet PHYs? They are both serdes aren't they? Why can't I speed up the pcie to ethernet data rate?
Using tools can do equalization or use compliance to check the channel but how can it be implemented at the transmitter and receiver?
I’m curious why we don’t see qpsk or Qam more often on wired interfaces??? Is it the latency of the processing? Expense of the transceivers?
Shouldn't -32db be factor 5 and not 50?
No. -32dB is actually around a factor of 40. 20*log10(1/40) = -32.
Play at 1.25X - you’ll thank me later.
Thanks for the suggestion, helped me to get through it
The Man makes me mad. İ need to watch hım at 2x speed
Great vid but when he compared PCIe to UART instead of the previous gen PCI he lost his credibility with me. I wish the sound was processed a bit more
who are you ?
@@AlbertRei3424 why? You don't agree with my comment?
