External Oscillator - chossing right capacitors
we are having a problems running
CY8C3866LTI-068 with external oscillators.
In our devices we are using
12 MHz external oscillator (core), and 32 kHZ external oscillator (RTC).
Can someone help me and
explain what capacitors I should use with them?
In documentations its just
written that they should be but there is no information about right capacitance.
I expect that it should be some kind of equation..
On developer kit I can see
that capacitors next to external oscillator are just on schematic, marked as
"not loaded". On board there is none of them.
When we were doing tests
with different capacitors (using equations that we thought that should work) it
sometimes work, sometimes not.
ps. there is no problems
when i switch it to use internal oscillator.
Thanks in advance for
