I worry about ADUCM350 External Crystal Oscillator.
Please advise me.
It's shown to 10P of a datasheet as follows.
It's mounted on an evaluation board as follows.
Two of capacitor 15pF is added to a crystal oscillator of 32kHz.
Two of capacitor 24pF is added to a crystal oscillator of 16MHz.
I checked BOM of an evaluation board.
7pF fits in with a crystal oscillator of 32kHz and 12pF fits in with a crystal oscillator of 16MHz.
In table 19, 15pF is indicated on 32kHz oscillator and 12pF is indicated on 16MHz oscillator.
Is a key word "symmetrical load"?
In 32kHz crystal oscillator need 15pF & 15pF=7.5pF.(symmetrical load 15pF?)
In 16MHz crystal oscillator need 24pF & 24pF=12pF.
Am I right?
