Hello sir.....
i am new in the field of controllers..... i have some doubts to ask....
The crystal which we are using ..its made up by which material?
Why we use capacitor with crystal in microcontroller circuit?
Ever tried to google for any crystal FAQ?
Or would that give too much information?
It isn't too uncommon that the term quartz crystals is used. That should give you an idea. Of course, there could be other piezoelectric materials used.
Why have burden capacitors? Not sure it can be answered unless you already know a bit about resonance circuits. Now would be a good idea to look at them nice crystal faqs available.
thank you sir.......
but as we know...property of piezoelectric materials(crystals)....
when we give electrical voltage to it.....it will give mechanical vibrations as an output......so how we are giving this mechanical output as a clock to our microcontroller ????/
We aren't.
The mechanical vibrations affect the electrical properties.
Google for the details if you're really interested...
Thnk u sir. . . I will sure search in goole . . . .2moro mornin. . . . B'coz . . . .i really want to know. . . . .how the uC is getting clock as electric signal. . . . . .from two terminals of crystal. . . . . . .though the crystal produces vibration. . . .
Quartz crystal oscillators were developed for high-stability frequency references during the 1920s and '30s - there is nothing new or ground-breaking here!
Any decent electronics textbook should cover it, and there's plenty of stuff online.
BTW: the dot key on your keyboard seems to be faulty...
Thnk u, . . . . . .nd no sir dot key is not faulty on my keyboard. . . . . .bt this is my habbit . . . .i used to do this when typin msgs on my cell. . . .
Sure sir. . . I will try to find it in google . . . . . bt sir can u plz suggest me any book or any link . . .about it. . . . So that i can clearly understand. . . . .wts there inside in the crystal . . . . .nd how it is giving clock pulses to our controller. . . . . . .
i used to do this when typin msgs on my cell. . . .
You in jail brother?
No . . . .man. . . i m nt in jail . . . . . . .dis is jus my habbit. . . . . . . . .
is that you do not waste ink typing all the characters in a word
Just type "quartz crystal oscillator" into google - how hard can that be?!
