Startup time of 32KHz crystal OSC

[slchen]

Hi all:


I would like to know the startup time of 32KHz OSC to oscillate.
several mini second ? or several second?


Thank you.

It depends on the circuit. But a typical start-up time for such a crystal would be many milliseconds. Maybe 30-60 msec.

How long is a mini second? :???:

So small that it is hard to see. But it lasts one second.

It probably has the same relationship to a second that a mini-computer has to a computer, or a mini-skirt has to a skirt.

Since I am a dirty old man, I also thought of a mini-skirt.:lol:

I used to be an apprentice dirty-old-man, graduated to journeyman status, and now am a Master.

You worked your way up very well. I have a PhD so I am a dirty old doctor, a gyn....

Thank you.

Depends on the circuit.

However you should expect ~Q cycles for the start up period
