- Why? Crosstalk depends on speed of rising / falling signal edge (how fast signal changes from low to high or high to low).

I have never before whatched 100 videos of a single channel in 1 day!
Thank you :)
I think your "one-tip-a-day" is a very good idea. I also think moving forward with your book is great. I think there is not enough practical books about signal integrity and routing. What I would very much appriciate are measurements and rules of thumb for radiated and conducted emissions, as well as crosstalk shown on actual examples with actual measurements so that people can get develop intuition on how things work.
Just one quick thing which I think is good to mention: Crosstalk is all about frequency, the reason that it happens with fast edges is the high frequency content in them. Showing the fourier transformation of a square wave shows very well that a slow clock with fast edges generates a lot of high frequency harmonics, and that is the actual problem. I think it is always good to explain some of the background.
Keep up the good work!
Thank you very much Daniel.

- I would love to play with these! Once, in future if I have some time, I am planning to try something like this :)

- I am sure you understand what I meant :)
Great idea Robert - looking forward to these and improving my PCB layout skills this year
thank you robert. very helpful .
Thank you for this tip. It's very useful!
Thanks Robert, very useful.
Congrats for starting this series! I find it really useful! Subscribed!
Thank you Alin :)
Great playlist!
Very nice idea! Our team is subscribing and will be watching it daily! Best To You Robert!
Thank you! Now, I will need to keep doing it :D
Thank you so much on this tip. Keep sharing
Thanks Robert! I also learned Altium from your videos. These tips are really advantage to me who doesn't have so much experience in PCB design. Also really appreciate your seven key steps in professional schematics which I reference and already applied in my design.
Thank you Han :)
Your tips are amazing for young designers, as well as people working in small companies, that do not have some kind of experienced senior hardware designers. Thank you for sharing your knowledge, I learned from you a lot
Thank you Grzegorz
These tips are great! would love to see more of these and would definitely buy your book if/when you release it.
Thank you very much Roy :)
Hi Robert, thanks for the tip. I'd like to see more of them :-)
And of course, happy new year!
Happy new year Pn :) Thank you for your support :)
thank you for these videos!
Thank you for your tutorial
Great job! I like your PCB design video very much. I can learn a lot of Alitum stuff from here. Please continue and I will support you and thank you
Thank you very much Ricky
It is great what you do!
Szia Ferenc! Nagyon hasznosak a videóid, sokat segítettek a szakdolgozatomban! Csak így tovább! :)
Happy New year Robert 🎉🎊🎉
Many thanks for this tips, and all other Altium's video. I really appreciate them.
About the video I suggest you to make them below 10min each. About the tools you suggest I propose to mention the paid and the free one's, and because experienced designers sometimes need options not available on the free ones.
About the book I like your idea, and agree with the color picture, they help a lot to understand what you are talking.
Again many thanks Robert, I wish you all the best for this new year !
Thank you very much Nelson. Happy new year to you and your family too.
After I recorded some videos, it looks to me like, most of the videos will be somewhere between 2-5 minutes. 1 minutes is too short and more than 10 minutes may be too long for everyone who is busy or at work. If I know a paid option for the free alternative, I will tell. Have a great day :)
Love you video sir
Waiting your book , Robert :) Will be useful for me
Still, you have already shared quite a bit of knowledge, and as aga1nst said, making money is not wrong. Having said that, I'd gladly pay 10-15$ for a copy of the book.
Thank you krokodyl1220. I am not sure how much the book will cost, but my guess is somewhere between 10-30USD ... not because of profit, but because of a lot of color pictures (pictures will be useful for many tips). So, I am sometimes worried, that even without any profit it may not be the cheapest book. But I hope, that the publisher will have some tips / techniques how to make the printing cheaper and I hope that today's color printing is not as expensive as it used to be.
Any thoughts on releasing en ebook on Amazon? (well, not necessarily there) Typical technical releases seem a bit awkward on ebook readers (especially if containing large quantities of equations or code listings), but it seems like the format of the book containg a lot of short tips would fit nicely.
I thought about ebook, but I am not 100% convinced about it. Some of the customers may be companies and they may prefer to buy the paper book so they can keep it in the company library and engineers can borrow the book between themselves. Also, I have bought couple of ebooks, but I like the real books more :) Honestly I do not know why :)
However, ebook sounds like good alternative to publish the book in case I am having trouble to find a publisher.
Well, you can do both ;)
I will buy the first edition!! Signed please! :D Next tip, best way to manage libraries (integrated libraries) between differents projects . Nice work Robert, keep on
:D Thank you for a nice comment :) I do not have any special tips about managing libraries - libraries are one of the areas where I have not ouind the best solution yet.
Thank you so much Robert, I like you very much :)
I suggest making each tip less than 2 minutes. Wonderful new year resolution! Your time and effort should be compensated. Thanks.
I was actually thinking about this and my guess is, that most tips may be probably between 1 to 3 minutes. Some tips may be longer, but I will be very careful about not making them longer than 10 minutes. Once I create couple of videos, I hope I will get the feeling what could be the right length. But you are definitely right, the length will be important.
thanks, great to know
Nice tips
Thank you Kinyume
hey Robert please keep going ahead with such videos and writing the book
Thank you :)
I want that book! :) when will it be out ?
Thanks for the tip, I'm looking forward to the series. And you know there's nothing wrong with making money from your book - we all work for money, it's understandable :) Good luck!
Thank you aga1nst for your support :)
Sr Feranec , i found very interesting your tip!!!!
You helpme a lot with 3D design with altium , designspark and 3D PDF for my latest school proyect.
Saludos from Guadalajara México 😃😆
Thank you very much Charles :) I am very happy you found the videos useful :)
Watching tip #001... You have done very well, thank you!
Did you finish your book?
I'm looking forward to buy your ebook. Keep writing!
Thank you :)
good.
So true!
As far as I understand, rising/falling time of a sharp signal has a massive impact on crosstalking, but the current has also a huge impact. For example, 1A low frequency H-bridge can intefere with anything nearby on the PCB.
Anyway, I find these tips very interesting Rob!
Thank you. BTW nice nickname :)
thanx bro
Good video.
Thank you MDF RESCUER :)
Greetings From Egypt :)
Keep it up and try to share the book on the eevblog forum
Thank you Abdullah. That is a good idea :)
trace capacitance should minimize the cross talk right?
Capacitance should take care of sharp edge at low frequency
Happy New Year and thanks for the new video!
I have only one question. How can Saturn PCB derive coupled voltage without load capacity value?
I have seen some calculators considering also impedance. Saturn probably uses the standard equations for two tracks routed close to each other - maybe approximately the worst scenario? For the exact calculation you may want to google for more precise calculators, but Saturn is just fine to get the feeling about how bad the situation can be.
Hello, Robert thank you for sharing such wonderful tips on Hardware as we as PCB designing. You Rock as always. I follow your every video and tips you give. In many videos, I found that you suggest the Saturn PCB tool kit, but I am unable to download it from their site. If possible can you please share the file or can tell me where can I find it?
Thank you Rohan. Here is the link: www.saturnpcb.com/pcb_toolkit/
Will gladly buy your book in ebook version sir.. :D
Please continue on working that books.. :D
Thank you Johan :)
Robo toto je dobry napad! Dvihne ti to sledovanost, subscriberov a teda aj prestiz. Podporujem tuto iniciativu!
Mozno by si mohol natocit naraz viacej videi a potom den za dnom ich uverejnovat. To len taky napad.
Dakujem za podporu :) Premyslam uplne rovnako, len aby som vydrzal co najdlhsie. Videa som uz teraz natocil 7 dni dopredu :) ale aj tak mi to trvalo dva dni :D Hadam ze sa zlepsim a postupne to nejako zoptimalizujem a zautomatizujem. Sam som zvedavy ako tento experiment dopadne :)
Robert Feranec Podla mna to ma buducnost. Vsetko dobre v novom roku!
Robert, is your book ready?
Hello guys,
Any one knows how can I get this book as pdf file?
I mean XYZ+ Tips for schematic design and PCB layout.
Hi Robert. Did you finish the book? Is it available somewhere to download or even to buy it?
No, I have not :( It was much more work than what I was expecting, so I rather focus on youtube videos. Maybe ... sometimes ... I would love to finish that book.
You are doing a great job! man.. I really appreciate you.. :)
Thank you Naval :)
Will the book be for purchase, robert? I am very interested in this as i'm a student.
I really hope, once it will be possible :) I have receive a lot of positive feedback from people, I will keep doing the videos, but it looks like I will need to finish the book now :D
Saturn PCB is really nice and easy-to-use software.
Yes, I will use it in some other tips too :) It's a good tool with bunch of useful calculators. And the best is, it is free :)
Robert Feranec Yes. I forgot to mention the best thing about the software :D
I like your voice....
Where can I find your book ?
Hi Robert, I have the same question, how can we get your book on tips? Thank you for all your work.
Actually sharp edge IS high frequency :-) Low bitrate/switching rate would be more accurate term than low frequency in this case :-)
