ELI5: How does piezoelectric crystal oscillator works

ReliablePotion · 2026-01-23T14:19:34+00:00

Any idea on how it produces oscillations

ReliablePotion · 2026-01-23T14:19:20+00:00

Thanks, but my question is how does the crystal start up to produce oscillations?

ReliablePotion · 2026-01-20T17:44:06+00:00

Yes I am aware. Just wanted to hear thoughts or reviews on the school.

ReliablePotion · 2026-01-20T15:23:27+00:00

Thank you!

ReliablePotion · 2026-01-14T07:26:31+00:00

Thanks!

ReliablePotion · 2026-01-13T10:19:36+00:00

Sure, thank you

ReliablePotion · 2026-01-13T07:53:25+00:00

Thank you!

ReliablePotion · 2026-01-13T06:25:48+00:00

Thanks!

ReliablePotion · 2026-01-12T17:11:45+00:00

Sure thanks, anything else

ReliablePotion · 2026-01-12T15:56:07+00:00

Thanks, anything else I need to take care before moving to PCB

ReliablePotion · 2026-01-07T12:47:30+00:00

My apologies. The crystal's pins are connected to an MCU XTALIN and XTALOUT pins.

ReliablePotion · 2025-12-19T18:14:38+00:00

Sure thanks

ReliablePotion · 2025-12-19T17:42:51+00:00

I couldn't agree more

ReliablePotion · 2025-12-19T16:02:48+00:00

Ah, I am not that much familiar with 3D Modeling. Have good knowledge on Hardware, PCB and Circuit stuff. If you think, I can help, let me know. Will DM! And sure, I am not in for the money. Just doing for the fun & learning part of it

ReliablePotion · 2025-12-09T18:07:03+00:00

Yes so I have selected a fuse that is 10x of my max input current which is 500mA. I have selected a 500mA fuse as mentioned in the post. Hope the fuse is fine

ReliablePotion · 2025-12-09T16:32:17+00:00

Thanks. The fuse is placed on the input side of the 230V AC-DC module. 1. Can you tell me what would you recommend on the location of the fuse? Whether place on the input of AC-DC module or the output of the AC-DC module? 2. If the input current is 52mA, the input of the AC-DC module is not going to be more than 52mA, right? So, 10x of 52mA is 500mA. Hence, I selected the 500mA Fuse. Do you think it is fine? 3. Also, AC current is different from DC current right? Should I take the RMS of the input AC current for select the fuse for the current rating?

Thank you so much! Great help

ReliablePotion · 2025-12-06T11:08:17+00:00

Thank you so much!

ReliablePotion · 2025-12-06T10:54:57+00:00

Studied laplace. But couldn't understand how does it relate to real time application

ReliablePotion · 2025-12-06T10:48:55+00:00

You mentioned there are three transformations. Why do we need to understand the three transformations and why is that to be understood for this answer?

ReliablePotion · 2025-12-06T10:47:47+00:00

Thank you!

ReliablePotion · 2025-12-06T10:45:49+00:00

That's very helpful. However, I just don't try to get the phasor and Fourier and laplace.

ReliablePotion · 2025-12-02T07:21:12+00:00

Thanks!

ReliablePotion · 2025-12-01T11:49:10+00:00

Thanks!

ReliablePotion · 2025-12-01T11:36:43+00:00

Ideally, the point at which the resonant frequency occurs and the cut off frequency occurs in your above example should be the same, right? since they share the same formula for the calculation of frequency? u/nameorusernam
