ADS8326: Regarding DCLOCK issue

Part Number: ADS8326

Hi support team all.

I received argent inquiries from our customer in the following.  

Could you confirm regarding these inquiries?

1. Potential risk of exceeding the specified limit (6 MHz input)

 If a 6 MHz DCLK exceeding the specified limit (4.8 MHz) is input in a VDD=3.3 V environment, is there a risk of any defects (Missing data, loss of accuracy, etc.) occurring in the internal operation of the ADC?

Also, is there a risk that such defects will become apparent in the future due to changes in environmental temperature or the lapse of operating time?

2. Risk of IC failure If operation with a clock exceeding the timing specification is continued, is there a risk that the internal of the IC will deteriorate and Is there a risk that it will eventually break down? 

Best regards,

DH
