Can somebody help me identify this crystal oscillator for a quartz clock, my guess is that it is a 32,768 Hz crystal but the code says S523 and I have no idea what it means.
It definitely looks like a 32,768Hz crystal. Never heard of any other values in this size.
In which circuit it's planted on??? If you have any table clock or wall clock, you can replace this crystal with the clocks one to see if it gives exact 1 sec tick...
