Crystal Value

Can you send me the part number of the crystals you are referring to?

ECS Catalog 2000 (ecsxtal.com) this is the crystal we use on the eval board.

Here are the 3 alternate Options that we are looking for:

- https://www.digikey.ca/en/products/detail/jauch-quartz/J49SMH-P-G-G-K-3M579545/17126811

The first 2 are OSC so they will work fine. The last one is a crystal with an ESR of 120ohms. This is fine for some load values not 30pf. The datasheet specs ESR 30min to 200ohm max. I have attached an XLS to compare the GM critical for the crystal we use to the one you suggest. You can use this with other crystals just enter the data in the xls.

Thank you for your response!

Looks like the gm comparison is for ADE9000, would it be the same for ADE7953?

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.
