No one show some interests toward this chip？EVERYONE only cares about output power？

I found it early this year, noted to someone promoting 700khz. The evaluation board is too expensive for me but I am looking forward for an affordable controller necessary only to initialize at start up. Maybe, a fixed options pre adjusted version can come out .

It says I2C diagnostic options. Doesnt seem like its strictly necessary for basic operation?

To choose the gain and frequency, the controller is needed only to initialize at start up. The document doesn't say what happens if used without. This is new technology, I am sure it will be implemented in near future on standard types.
