ADS9224R: ads9224 sclk frequency

Jason Haedt

Part Number: ADS9224R

Hello,

In the datasheet I see the recommendation to increase the voltage on the digital domain if operating greater than 20MHz. We are operating exactly at 20MHz and wanted confirmation that 1.8V is an acceptable voltage rail to run at.

Hello Jason,

Thanks for your post.

It is ok to operate with a 20-MHz SCLK AT 1.8 V DVDD supply. Generally there is already some margin and operating above the minimum 1.65-V will provide additional margin for proper operation of the digital core.

Regards,

Ryan
