Measuring and Simulating QUARTZ crystals using LTspice

#126 #ltspice
In this video I look at how quartz crystals can be modeled using LTspice. Considering there are not a lot of available models out there, afterwards I look at how the necessary parameters can be measured on practical components.

Thank you for creating such an insightful video on quartz crystals. its rare to find content like this! it helps to understand crystal better. and uses LT spice better.

Man, you keep on hitting the topics that overlap with areas I work in, but don't always have time to dig into as deeply as I would like.

[peasant]

Excellent video. This channel is an underrated gem.

[wojtekkrupski]

I'm embedded programmer and I want understand electronics in deep level. Your channel is very informative. Thanks a lot!

[xAF]

Amazing presentation, FesZ! You really are among the very best electronics educators on YouTube.

[codijack]

The best explanation I have ever seen! Your series about electronics and the way of explanation is very communicative and easy to understand. Keep on going and ... stay academic teacher :)

[DavePKW]

I really learned some things about crystals here. Thank you!

[AndrewKiethBoggs]

Amazing and informative video once again. Thanks Fesz!

[sebastiandeleon]

This tutorial is top quality! Thanks so much

[ResonantGamingOneHive]

Hey Fesz, very nice and informative video but can you elaborate or provide a schematic of the test fixture you built?

[alexloktionoff]

Can you demonstrate working LTSpice simulation of Colpitts XTAL oscilator?

[ChaseNoStraighter]

Nice job! I’m wonder if series load capacitors set up in a pi configuration are not more common.

It's getting kind of creepy. Once again we are working on exactly the same subject, haha.
I was just diving into the same subject to make a 6Mhz simple sine wave generator.
Well explained video, thanks 👍🏻😎

[danielkohwalter]

Very nice videos! Keep going!
What about make the same parameter identification with more common equipment like a signal generator and an oscilloscope? How would you do it? What are the caveats?

[krishnasa]

Excellent explanation, Is ESR the main component of a crystal for its energy dissipation? thank you very much.

[alexgreysukh]

If possible, could you please refer to how you have derived the motion capacity formula from 2 parallel resonance frequencies (11:50)? Using a common quarts parallel resonance frequency formula, I am getting another expression...

[paulpaulzadeh]

you didn't put jitter model inside model ? did you ??

[SurvivalSquirrel]

A 400$ tool only has a 10MHz Signal generator?

I tried to simulate a colpitts oscillator with 100Mhz quartz oscillator, but I failed . I did a quartz model that function in simulate but it not funnction in colpitts oscilator . The colpitts oscilator is that presented in @devttys0 cannel for 12Mhz but I tried to adapted it for 100Mhz and I do not had success
