Differential signaling was a silent take over on computing pretty much. Until the pentium era, basically only ethernet used differential signaling. But then USB,sata,pci-e,displayport/hdmi... One by one, every PC connection was replaced by another standard that used differential signaling for better performance.

[@jtadevich]

interesting

[@ArcaneArbiter]

Thank goodness too. It's a simple but rock solid signaling technique

[@gamagama69]

i guess thats why we still use it all these years later

[@fRutrn]

out of curiosity, is it used for traces on motherboards?

[@foogod4237]

Actually, differential signalling was part of some serial protocol standards (such as RS-422, common in many industrial applications, and also used by some early Macintosh peripherals) since at least 1975, and I believe Low-Voltage Differential Signalling (LVDS) was already widely used in laptop displays and SCSI hard disks in the early-to-mid 90s. But yes, as speed requirements increased in general, pretty much everything went to LVDS because it provides much higher reliability for high-speed data over a given distance (nowadays differential signalling is even often used for some types of communication channels inside the silicon of CPUs and GPUs, too). Of course at the same time many things also went from parallel to serial too, so the transition to differential signalling for lots of things actually came with fewer pins, not more (which is why many modern PCIe cards have much much fewer pins than older ISA/EISA/VLB/AGP/PCI cards did, etc).

[@hubertnnn]

You forgot to mention that while its possible to send data two ways using the same cable (or the same differential pair) you usually need to wait between messages to allow traffic from the other side (similar to how it works with cars). That's why you usually have 2 (or more) differential pairs each going in one direction only. And if traffic usually goes in one direction, then you can have an asymmetric connection (eg. 3 pairs going in one direction and just one going in the other). A good example is ADSL internet (though the asymmetry is usually deeper in the network) that has more connectors for downloading than for uploading data.

You forgot one of the other main reasons why there are so many pins to transfer data, especially with cables and PCIE cards. The reason is because they can't drive the data transfer speed too high or the cable (and even the tracks of solder on the motherboard) begin to send out RF (radio frequencies) which causes interference and issues with many other devices. The reason why CPUs can get super fast clock speeds in the Ghz range without this issue is because the components are all super close to each other and on the same die. When you need to transfer data to a graphics card though, the clock speeds have to slow down to go the distance. To keep bandwidth high, they just add more lanes to PCIE since they can't turn the frequency up any more.

[@lawrencedoliveiro9104]

And yet gigabit Ethernet works fine over unshielded twisted-pair wiring.

This is completely backwards. Clock speeds go up at longer distances. SFP28 has up to a 28GHz clock, much higher than any CPU, and transmits over several meters of Cu. Even PCIe 4.0 (a common CPU-GPU interface) clocks at 16GHz. PCIe has had regular increases in clock speed, from 2.5GHz with PCIe 1.0, through 5, 8, 16, and 32GHz with PCIe 5.0. PCIe has never added to the 32 lanes originally specified and only x16 lanes are common.

The original serial port had 25 pins, even though at it's most generous only ever used 11, why? Because the first person to build a computer with one had a bunch of surplus 25 pin plugs so that's what he used, then everyone that came after had to follow suit or break compatibility, eventually 9 pin for serial won out as a more popular standard but even it had most of it's pins dedicated for rarely used and not entirely necessary functions.

[@albertoedgar831]

slow clock = less data = need for pins aka 12pin 600mhz = 24pin 300mhz (i think)

[@foogod4237]

Putting power and data on the same pins doesn't "cause interference" (if done correctly). There are actually several common applications which do exactly that and work just fine (such as Power Over Ethernet). The real answer is just that it's _easier_ to put them on separate pins because that way you don't need additional circuitry to combine them on one end and separate them on the other.

[@johndoh5182]

You really didn't mention the shielding thing with detail, and the detail is short. Data signals that clock at high speeds will both be subject to interference from the other lines in the cable and ALSO any strong signals in the room. Those high speed signals ALSO will generate interference into data lines in the same cable. So, data lines are twisted with a ground line which helps to contain the signal, and for this you have to understand inductance but that's above the scope of this video. Data lines, for which most data cables have a few, are wrapped with a ground line to make a twisted pair and this creates the shielding needed inside the cable bundle. The ENTIRE cable can also be shielded to reduce the ability of an external signal being propagated into the cable, and this is important if you're in an area where there's a lot of external transmissions.

I'm a big fan of DVIEIO, myself.

From Montreal Canada! Riley is the best presenter of the gang.

[@NickoTyn]

So all those people over at indiegogo payed money for a product that doesn't exist, but the money is used to pay for advertisment.

[@chronosschiron]

the neck cooler is first commecial add ive seen that i actually watched instead a skipped

[@jacekicksass]

Interesting video....but that sponsor 😂😂😂 How little self respect must a person have to wear such a thing??

[@henryzhong1989]

AICE 3 looks modern and premium (Gundam style). I tried it myself, restaurant waitress ask me which brand of neck fan it is, pretty cool.

[@briiandee]

Riley slangin info like a G.. You love to see it

[@unrealed]

What kind of monster puts a B on the left and an A on the right for "A to B"? I know he gestured that way, but just flip him for that shot!

[@Aperez]

When USB-C hurts me more than the flash warning.

[@GodlikeIridium]

0:54 modern CPU don't have pins anymore at all 😊 They have tons of pads, connecting to pins now being on the motherboards. Installing the newest EPYC must be a nightmare to install with each single pad having good contact... 😮

[@itsdeonlol]

Thanks Riley!

[@wodstalker2819]

This feels like an april first sponsor

[@henryzhong1989]

RANVOO brand has existed for over 10 years (founded in 2012) and it's now the largest brand of personal appliances in China. AICE 3 is its 6th generation of neck fan products, and the 3rd generation of neck air condirtioner. So both the brand and product are real not a fraud.

[@wodstalker2819]

@@henryzhong1989 i never doubted the fact it exists, but im doubting its usefulness. It feels like an over engineered solution to a very basic problem. That's just me though

[@wisteela]

I was thinking why 12 volts now, then remembered lower voltage is higher current.

Lol did LMG just advertise a scam kickstarter project

For data and information transfair between computer hard ware And I think sockets without pins is the best sockets And simple and the data and information are transfair explanations but with pins when any pin is broken then data and information will not transfair excellent.

[@doctorhowdy1194]

that cable example is really bad because in europe all cables, even the cheap ones must endure ~3600 watts

[@nachtmondvogel2480]

but what about SDI cables, they only have "1" pin? would be great to get explained

[@MaximNightFury]

The outer part is the ground, the inner part is the Serial of the Serial Digital Interface

[@hubertnnn]

SDI has 2 pins (one inside for signal and the other is the screw for ground) and it can only send signals. Though there is also a standard called "1-wire" that while using 2 pins, it can transfer both data and power via the same pin.

[@Duncan-Donuts]

They are needed to transfer more data for our sponsor

[@Haarba1]

"Why not?" - this answer was always sufficient for me :)

[@philash824]

I was quite happy to carry on thinking that these kind of things worked because of witchcraft

[@SkylinegodzillaBen]

Wish you could explain more about differential signaling and how it works. I've quite often just used things like pwm for my microcontrollers so most of my stuff just uses 3 pins 2 for power and 1 for data.

[@bandbigred]

I’m going to surmise it’s the same idea as a balanced audio cable, having the signal 180° out of phase with itself means that any interference that gets picked up will be cancelled when the inverted signal is inverted again at the end.

[@roygalaasen]

@@bandbigred yes, and there are lots of videos explaining it well on youtube as well, but I think OP means that they could have explained it a bit more in this video.

[@msrdo20]

the writing that suggested the other cpu video was good

[@mcpr5971]

Ok, so for an N-thousand-pin CPU socket, why not have the 4 perimiters "voltage bars" that handle +v and gnd? Why N-times-1-pin instead of bar-with-n-pins? then they would only need pins for data/clk ? Similar with power supplies? Why not have Big-Gauge-wire-and-connector instead of 12-small-pins X2 for +v and gnd?

[@stefanengler772]

They forgot the dallas 1-wire and the plc protokolls. It's possible to have only 2 pins but it's hard. The 4-Pin I2C /TWI is one of the best interfaces (sd-cards for example). It would be great to have 2 wires only but the industry don't want to come to one standard. 1 GBit/s over 2-wires (with power) where possible 10 years ago (PLC; ok there where some flaws and you need to reboot this things every 3 month or so but it worked and could be resolved).

[@George-lb9gn]

Why is there no techquickie for how usb works? Would be a great video!

[@Apocalymon]

There is, several in fact. Did they remove them?

[@George-lb9gn]

@@Apocalymon no those videos are just on usb connectors

[@vladislavkaras491]

Thanks for the video!

[@Stealth86651]

Man, that neck cooler advertised. Seems a bit insane to have a lithium ion pack of that size resting against your jugular. Would be quite a scene if that were to go up.

[@pit32]

Everyone got one half the size in their pocket.

[@munjee2]

Yes half, and in their pockets, exactly

Take it easy, the battery of AICE 3 is customized to be compact and safe. It has passed both our internal safety tests and external safety certificates (including FCC and PSE etc.)

0:50 *"Resistance is futile¹."* (displayed in a comic-book-style _speech bubble_ on screen) ¹ "RESISTANCE IS FUTILE" was first Trademarked, by Paramount Pictures, in the 1990s. CBS Studios currently holds the Trademark. I would post links to sources, but then my comment would be auto-moderated away. I guess... as part of KZbin's _blame the messenger_ policy. I don't know it for a fact, _that's what they call it_ - I just _know it to be true._ smh
