Hi team,

The frequency of the LMK05318 crystal oscillator not use 24.576, if it can be used with 25M?

Hi Enhui,

Can you clarify what the question is? I would recommend using 24.576MHz as the XO frequency if possible. If the XO frequency is 25MHz then the DPLL cannot be used since the XO must have a non-integer relationship with the BAW VCO frequency of 2500MHz. If only the APLL will be used then it should be ok to use an XO frequency of 25MHz.

Regards,

Connor
