Crystal Value

Category: Hardware
Product Number: ADE7953] recommended Crystal part# or on EVM, ADE7953


We are trying to find a similar crystal oscillator but having challenges in finding one with the exact capacitance value.

Can you please help answer below questions:

-  Can we use a 15 pF or 30pF capacitor?

- How the accuracy would be affected if the cap value is changed?

- Planning to use similar 3.579545 MHz ±25ppm crystal.

  • The calculation is the same for gm critical as the ade9000 and any other part that uses a crystal. This is more a crystal calculation. I calculated the gm for the crystal we recommend, just have the gm critical lower that the one we use, and you should be fine.
