RadioS Question

Nov 18, 2022 00:00

Hi Dave,

I'm not sure about data related to ADAU1452 xtal. In ds they put 22pF as C1 and C2 and summing with Cstray (2-5pF) you obtain a CLoad between 13pF and 16pF.

Then in the EVAL the Y1 ordering code shows an XTAL with 10pF load capacitance, with a note "18pF".

Could you help me with this issue?

Thanks

Dario

Hello RadioS,

Sorry for the delay in response.

If you are designing a board then we would recommend copying the part given in the eval board. Because it's been very stable design that we have used for years. So, use the part number given in the eval board manual.

Regards,

Harish
