Capsense PRS switch frequency
"CapSense® Sigma-Delta Data Sheet" says:
average is FIMO/4,
peak is FIMO/2
What is the center frequency. Is it FIMO?
I don't think so. I bet rather FIMO/4(switching phase alignment). So the freq spec is 0 to FIMO/2. Is it true?
I don't think so. The highest freq range for PRS is a clock speed.(PRS is not clock doubler)
What should then be the right answer?
I think the right answer is below:
average is FIMO/4/4,
peak is FIMO/2/2
