AFE7950: Timing Requirements Question

Jack Zhang

Part Number: AFE7950

Hi,

I am referencing the TI AFE7950 datasheet that I downloaded from the secure site. Are there minimum specifications for the setup and hold times shown below? Thank you.

Hi Jack,

I am checking with our team to see if we have any additional data.

Hi David, Just wanted to follow up. Do you have any status on this question?

Hi Jack,

The values given in the datasheet are actually max specs for SPI. We will be changing this in the next revision of the datasheet. The max spec should be what you are looking for as the invalid timing window needs to be speced for the worst cast "max" for covering PVT.

Thanks for clarifying. Are there min specs as well?

Hi Jack,

Max or worst setup and hold time specs determine the valid timing window. There's no need for min values for these specs. So, we don't plan on measuring min specs.
