Hi everyone,
I need some advices to evaluate which resistors/capacitors values would be
most appropriate for a 32.768KHz oscillator using a 4521 CMOS chip.
The closest example in the datasheet is a 50KHz crystal oscillator. May be
the 18M / 750K / 82pF / 20pF values are ok for a 32KHz crystal but I don't
know for sure. The crystal I got is quite small, very thin cylindrical size
that could fit in a watch, that's all I know about it.
Here is a link to the Motorola MC14521.

I pick this I/C because has built-in dividers.
