ADS7867: The difference of tc(sclk) between high VDD and Low VDD

Genius 3190 points

Part Number: ADS7867

Dear Technical Support Team,

Why does ADS7867 have the difference of tc(sclk) between high VDD and Low VDD?

Does ADS7867 have unusual  architecture?

Datasheet shows that the higher VDD is, the lower tc(sclk) is. 

Our customer'd like to use much larger than 6.7us with 3V , if possible.

In other word , more slower frequency(Hz) than datasheet spec of tc(sclk).

Typical ADC doesn't have maximum tc(sclk) spec, but this device have them and the limitation depending on VDD. 

Best Regards,
