HI, this class (Part 1) is audo archived (see the player above) and the slides have been updated (under special educational materials). Enjoy!

Blogger

Thank you Ransom and Janine

Rookie

Better late than never

Rookie

Thanks Ransom ! That was a very insightful presentation !  

You mentioned that  scrambling is required for 64B/66B and 128B/130B encodings to minimize the CID length. Can't scrambling alone be suffice ? Why additional encoding is required ?

Look forward to your tomorrow's class.

Okay, I'm outahere. "See" you tomorrow!

I've seen people manage 32 Gb/s and have heard of 40 Gb/s, but never seen it first hand on more than 3-4 inches (7-10 cm)

I don't know the answer to "How high of a data rate do you think we can get on, say, a foot of standard FR4 PCB?" I was hoping you would ; )

 

data rate: 250 kbps

Rookie

Hi Alejandro, I'll make that request to the powers that be! It's a great suggestion. What I do know is the titles are tied to your EET profile.

Blogger

>>How high of a data rate do you think we can get on, say, a foot of standard FR4 PCB?

What was the answer?

@JanineLove. Can we get the nicknames changed from ROOKIE to GUEST and the presenter to PRESENTER

Or, you can post your questions here and we can get to them after tomorrow's class. Thanks!

Blogger

Thanks everyone for joinging in, I think we're donw. If you have anything else, send me a note: ransom@ransomsnotes.com

How high of a data rate do you think we can get on, say, a foot of standard FR4 PCB?

 

Yeah. I'd rather be right than wrong, so please don't be shy when you catch a mistake.

i understood, just wanted to clarify regarding tht error. Also a good presentation to revive the concepts back :)

Rookie

Thanks Ashwin and Drew. Guess I spaced out while goofing around in PPT drawing utility.

It will continue to be wrong all week, I'll point it out and try to employ a different wisecrack each time.

Fortunately, one of them makes sense for feeding a VCO!

Rookie

If you missed the beginning of this class, or want to hear it again, the archived audio is avaiable now.

Blogger

Thank you for the presentation. Looking forward to tommorow's.

Duh.

Good catch. I wrote LPF on my PLL clock recover slide, which is CORRECT! but drew a HPF which is _wrong_

 

lets say slide 20, bits it mentioned wrong in all i guess.

Rookie

Wow such data rates.

Thanks see you next class

Rookie

slide 20 - PLL diagram - has "LPF" filter

Rookie

Thank you. I have had some exposer to testing in the past and what you refer to as the eye was call the bathtub curve display on the analizer.

Have a good day very good presentation

Theo

Rookie

Hey Ashwin, wich slide do you mean?

 

Indeed, LPF block seems to be HPF

Rookie

Thanks for the presentartion

 

Rookie

I see a lot of people doing work on advanved generations of PCIe and USB.

Wondering how you feel about PCIe no longer  requiring "distributed reference clocks."

 

USB 2.0

Thank you, Ransom, Janine

Rookie

Thanks!, good presentation

Thanks, Ransom/Janine.

Rookie

i have a question, why is LPF block depicted wrongly ? 

Rookie

Very interesting Ransom

Rookie

Thanks Ransom for the "introduction"

Rookie

Currently testing JESD204B interfaces.  Receivers on DAC's and Transmitters on ADC's

 

Rookie

Thanks Ransom, I finally got through the firewall and was able to listen in the last 10 minutes. This was informative.

Rookie

Thanks Ransom and Janine!  

Rookie

Nice point from Drew, we'll go into the distinction between digital and anlog tomorrow. It will involve zip-lines through jungles!

 

Yes, PCIe Gen 2, SFI (10Gbps).  PCIe Gen 3 on new project.

 

Rookie

Thanks. Very good intro.

 

Rookie

I work for a company that tests high-speed signals- QPI, PCIe gen3, USB3 using JTAG.  We are able to look at the "eye" at the dye using the embedded technology.

 

Rookie

Dance the jitter bug, or is it the hustle?

 

Analog vs digital engineer - At this sort of data rate, circuit design needs both, in terms of clean power and decoupling, low noise techiques, etc.

Rookie

thanks that was very good

Rookie

we provide usb 2.0 applications testing on our scopes

Currently testing DP 1.2 at 5.4Gbps per channel (4 channels).  Most issues with Random Jitter and ISI loss.

Rookie

usb3, dp1.2, sata, sas, fc

 

Rookie

USB 3.0 and PCIe Gen2

 

Rookie

Interested in hearing more about interconnect/channel impact on 28G generation

Rookie

Using Chrome Version 29.0.1547.66 m. It did have some trouble buffering in the beginning, but now it seems to be okay.

Rookie

I'm working on USB 3.0

Rookie

USB 2.0 certification testing

currently involved in testing 10Gbps Ethernet (10.3125G)

Rookie

audio just started working for me. only works in chrome and had to unplug and plug my usd headset. hope this helps. I'm using x64 machine

Using Chrome on W8x64 with no problems.

Rookie

why is LPF block depicted wrong ???

 

Rookie

Dance the JitterBug!

 

Rookie

Do you consider yourself more of a digital or analog engineer?

Blogger

I am going to leave this seminar.  IT is too hard to listen with all the audio dropouts.

Use Webex - it works for large presentations.

 

Rookie

this topic of this seminar is really good, but the method of delivery is intolerable

I spend more time pressing play than getting to listen.

 

Rookie

Roland, archive will be immediatly available after the live show

 

Rookie

Chrome is not authorized web brower.  Sigh.  Guess I will wait a month or two for the recording to come out.

I can see the minus sign.

Rookie

Both IE7 and Firefox do the same thing.

my audio got stable now. I am using chrome

my audio keeps stopping and I have to hit "play" many times to get it to continue

 

Rookie

Have tried on IE as well as Chrome and it's still blocked

 

Rookie

My pdf has a minus sign.

Rookie

Load & Clear with IE7,

 

Rookie

Too bad. This really blows but I can't hang around all day for this. Amateur stuff EE Times.

Rookie

No audio.  Errors on web page.    Audio bar announces 'BlogHost Radio' then stops.   A refresh of the web page just repeat the same.   

I have to press play button every 1 min to listen

The audio is working for me

Freelancer

Perhaps change browser to chrome or firefox, they seem to work best

Rookie

no audio on my end either. just downloaded the latest flash player and refreshed a bunch of times

 

I still can't hear anything. Could they possibly have made this more difficult ?

Rookie

Good evening from the other side of Atlantic in Valladolid, Spain; sad without 2020 Olimpic Games

we are working on 12Gbp

 

Rookie

10Gbps in production, 28Gbps in design

Rookie

I refreshed, but my player did not come up.  Still can't hear.

Rookie

why do I have to keep clicking the play for audio to play. it keeps filling the progress indicator and when full the audio shuts down

then I have to click

 

Rookie

Anritsu FAE... Supporting customers working between 14Gb/s and 32Gb/s (serial)

try refreshing, and Firefox is the preferred browser

Rookie

me too...cant hear yet

 

Rookie

@Jomo  try refreshing and hitting play on the player

Rookie

Good Morning

Guten Morgan
