Hello,
According to datasheet(page 66), load capacitance of 25MHz Crystal is 25~40pF.
My customer confirmed the crystal which they will use is obtained by 10pF matching by the crystal maker.
(Question)
(1) Is there any problem with 10pF as Load Capacitance?
(2) According to application report(SNLA290) (page 8), recommendation load capacitance is 8 pF ≤ CLOAD ≤ 20 pF.
Or according to application report(SNLA079D), requirement of load capacitance is 15~40pF.
Which is correct? Datasheet? Or Application report?
(3) According to datasheet(page 65), 20-pF load crystal resonator should be used.
But load capacitance of 25MHz Crystal is 25~40pF in datasheet(page66). Which is correct?
