The Data Clock and the CPU clock are related only in that they are both derived from the System Clock; they operate independently.
The Data Clock and the Average CPU Overhead are related by the Sample Rate. A sample rate is determined when the user sets the Data Clock in the User Module. The maximum Data Clock rate is 8 MHz. The following equation displays this relationship for the DELSIG11.
Data Clock = (4 x 256) x Sample Rate ; where the maximum Sample Rate is 7.8 ksps (minimum = 125 sps)
The Average CPU Overhead is determined by the following equation:
AverageCPUOverhead = (623 x Sample Rate)/(CPU Clock)
