AM2434: Clock and Data Input Specifications for the Sigma-Delta Function on the PRU Core

We are currently implementing a Sigma-Delta function on the PRU core of the AM2434, as shown in the attached block diagram.

Could you please provide any specifications or guidelines regarding the clock feedback input from the clock buffer and the data input from the Sigma-Delta converter?

We would like to evaluate the signal waveforms on the board we have developed. However, since we do not have criteria to judge whether the signals are acceptable or not, we are unable to make an assessment.
