Tool/software: Code Composer Studio

Hi
I have a few questions
How does the frequency structure or oscillator work? How do I identify its internal function?
How do I determine the sampling frequency ??
Where to search for this  and get complete information?

    I recommend reading the clocking and ADC (assuming you're talking about ADC sampling frequency) chapters of the F2837xD technical reference manual to get more information on these subjects:

    Additionally, I would import a few of the ADC examples from C2000Ware (under driverlib\f2837xd\examples\cpu1\adc) and look at how they set up the clocking. For example the Device_init() function calls SysCtl_setClock() that configures the SYSCLK. In the example you should also see a call to ADC_setupSOC() which configures the sampling window among other things.
