Hello Experts,
We have this query from client:
We want to change the input clock of the ADC dynamically in my design, so that after a number of clocks the device samples with the new frequency. During the frequency change (~ 75 mS) the input clock of the ADC is stopped. Questions are:
1. Can we stop the input clock for this time ?
2. Are offering the new clock to the ADC, do we have to wait for some clock cycles or can I use immediately the output data ?
In the table above the minimum input frequency is 1 MHz.
In the text above TI doesn't recommend the input frequency below 5 MHz.
These two statements seem contradict with each other. Question is:
3. What minimum frequency shall I use for my design ?
Thank you.
Regards,
Archie A.
