Ground in PCB Layout - Separate or Not Separate? (with Rick Hartley)

Do you separate Digital GND and Analogue GND, or not? What do you think is better?

Since graduating university I've been extremely frustrated at the slow pace and lack of learning opportunities in employment. This is gold, the stuff that companies want to drip feed over a decade, and even then it might not be right! Rick has done a great service in sharing his knowledge.

I'm electronics engineering student and the things I learnt from this video is priceless. These are the things you can not learn in university (mostly). Thank you.

[piscopatos]

thank you Rob. This is great. World needs people like you.

[Usturam]

I hope you to be very rich Robert. But these lessons you share with us are more important than money. Thanks for everything.

Two of 3 people I owe my job in the defense industry to... Thank you Gentlemen

Robert, your questions were right from the industry’s heart, you were a great host, please keep making more content like this..

That was extremely interesting. I would really love a video with Rick going over some BS found in switching mode power supplies application notes or layout guides.

More like this? YES! These are very interesting and informative. Grounding, EMI and these sorts of issues will never go away. Every new design opens all new opportunities for these issues. Hearing this stuff repeated and taught should help everyone. Thanks Robert and Rick - great stuff.

I’d like to see a video discussing grounding around connectors more. You see terminations around connectors that separate the connector ground from the PCB ground all the time for ESD or EMI reasons. You see 4n7 caps paralleled with 1Meg resistors. Sometimes you’ll see ferrite beads in the signal ground path and in the power path. This can help with emi but can hurt esd. A lot of times you end up with connectors or chassis that you cannot tie the connector shield to anything. Especially with hdmi, usb, Ethernet.

Do I like the kind of video's where you discuss topics with different people?
Yes!

Hi Robert, your idea of interviewing experts, like in this video, is excellent! It helps confirming some already known facts, and also shines some light on some new problems that we have with hardware design. Keep going, I love your content! 🙂

Wish I watched this video 15 years ago. Could have saved me a lot of sleepness nights, frustration and money. Thanks Robert and Rick, true legends...

I was recently allowed the great privilege of attending a 1-day seminar taught by Rick Hartley at the AltiumLive Design Summit in San Diego. Those 8 hours completely changed how I viewed PCB design, and electronics as a whole.

Great material. It answers my million $ question of how to connect the Shield layer of a cable and understand connecting the Chassis to earther ground is not important. Thank you!

[ThoriumBorium]

Thank you.

I'm doing a simple functionality test on a ntsc sync separator to confirm that the back alley website they came from isn't lying about what they are.

The part has separate analog and digital grounds, but every application I've seen shorts them to the same ground plane.

No other parts on the board to risk interference.

Great video...Rick is one of my favourite persons...I learnt what exactly differential lines mean from his webinar at Altium Live....Thanks for the video robert..!!

[abhichokshi]

Bursted all my myths regarding analog and digital ground.
Rob i will remember this video through whole of my career.

[bitterescape]

I love your recorded videos that are done interview style with industry SMEs. The way you ask them questions is helpful in enhancing the video watchers understanding on the topic. Thanks for the awesome interview!

[MichaelLenz]

Very helpful and valuable information! Exactly what I’m doing right now is the emi and proper grounding.

It would really amazing to have Rick, you and an ASIC signal integrity expert discussing the differences between signal / power integrity as done inside an ASIC EDA flow, and at the PCB layer, and then discussing the intersection between the two (e.g. decoupling capacitors on die, on package, on PCB, ..)
