Hi Kygo,

Could you provide the design calculator. It would be easy for me to verify the tank design and other components around the IC if I have it.

Could you also provide the PPMID as well as the expected sales opportunity figures. We use these for our internal metrics.

Regards,

Manikanta P

Hi Kygo,

Could you ask the customer to fill in the design calculator (https://www.ti.com/lit/zip/sluc675 ) with all the parameters used for the schematic. The schematic doesn't show the tank parameters or resonant tank frequency information.
