They say “timing is everything” and the piezoelectricity of crystalline quartz, coupled with a positive feedback oscillator, provides a reference clock for that “everything” from FPGAs to deep space satellites.
Let us show you how heaters with thermistors or varactors with ASICs are used to stabilize the frequency to less than a part per billion over wide temperature ranges, radiation environments or crazy shock and vibration conditions.
thank you very much
The first computer chips were like this, they used meteorite or crystals I think, and just wrapped wires around it, and encased it in rubber.
Adding positive current to one exposed wire, travels through and out to a different wire, and vice versa.
And then you connect that to switches, that make contact, send current, and affect another device based on their charge.
Which sounds basic, but until you hold a crystal, wrap it, and leave some wires, just a random ammount exposed, then you wouldn’t get the logic of it.
But to get to computer chips, you’re just screwing around with magnets and crystals and batteries, till you get a circuit board, that uses buttons to control… an airplane? Depends on the ammount of buttons, and what they activate.
Wow, the most visually appealing explaination video ever!
Nice
Thuoght it was Alex Jones for a second
Wow… I’ve never seen so beautiful and understandable video about quatz! Thanks!
That was good. Crystal oscillators are cool.
Since the crystal leads are reversible, what exactly does the ground connect to? I figure I’ll find the answer before a reply but other people may read this and want to know as well. Cheers!
I have a few questions, if you don’t mind educating me on it. You’re talking on how we get this energy from quartz through human manipulation of it. Does this also happen to it in nature and how powerful is this energy from it, especially when there’s an abundance of it for instance where there’s lots of limestone in the ground, and does flowing water over it seem to amplify its energy?
I now know more and understand less. Or maybe it’s the other way around. Either way, good video.
Awesome
hey howd the hell he know i just used a lighter.. literally right when he said it.. wtf lolol 1:20
It vibrate and sets cerain frequency,in radios,computers so on.
If want to listen to policec on a crystal radios than you buy that frequency. Same on mother board sets the cpu frequency through the board.
Have U got how a Quartz watch (Analogue) watch works?
Say i was to carve out a 60ft obelisk made of quartz, and had that sitting on a quartz base that was drilled down into limestone channels with a tidal river filling those channels. Would that create energy?
I am certainly a crystal thief from now on.
Thanks for the info!. Quick question please – how important (if ever) is it to get a very precise crystal oscillator? I ask because I see some selling online – for example – a 4.0 MHz and then there might be another that is 4.125MHz… is there anything important to note about those that are specified down to the 1000th or 10000th of a decimal point?
Thank you so much
Hi! I have 2 questiions:
1. The volatage applied to the crystal isnt constant?
2. If the crystal has 2 terminals for voltage , how does the ciruite measure the oscillations?
Thanks!
mmmm, i think ill watch this awesome video again, maybe some more will sink into my brain, thanks for this 😉
ahhh, so those electric lighters have a extensional crystal in them? see there is hope for me still, just not my brain… …
Wooww!!
I was searching this kind of explanation for a long time. Thanks!!
But I want more explanation about clock signal generation in microcontrollers by crystal oscillators.
Sir please explain the hormonics in crystal oscillator
Not a good explanation, I don’t like it. Everithing has an own frequency, from this point it is better to explain. Ping a glass, and you will understand…..
the production quality of this is first class
If clamp tighten or loosen control the response of crystal

Please teach basic electrical theory just like this for electricians.
