Hi,
I‘m not sure should I add 1 capacitor on OSCI or 2 capacitor on OSCI ,OSCO pin? Is it 8pF too small?
The crystal CL is 12.5pF.And the crystal is nearly close to the PCF8563 pin.
As the Datasheet tips show Cload= [ (Ctrim*Cosco)/(Ctrim+Cosco) ] should I add 1 external capacitor 22pF on OSCI pin just fine ? OSCO pin no need external capacitor because OSCO has already have internal capacitor?
thanks!
Solved! Go to Solution.
No exactly value but around 600mV.
Please refer to below picture mentioned value:
What are the requirements for the driver level of crystal ?
Is it continuous drive the crystal?or just in start-up?
It is the continuous drive internal of IC.
Another question,What is the operation voltage range in OSCI (Oscillation amplitude)and OSCO pin?not absolute maximum range.
