Dear friendswe know that fs=f(MCLK)/2*TA*TB and fc6.8k/TA we know also that 4<=TA<1 2<=TB<c TA*TB must be integer,so if we take the minimum and maximum values of TA and TB we get at that time 2.654kHz<= fs<d8kHz from here we see that the maximum sampling frequency that we can reach is 648khz. My questions are: 1-in the data manual(TLC320AC01C,page 1-7 after the control flow diagram)it is written there that the maximum sampling frequency is 43.2khz. what is the real maximum sampling frequency that I cannot exceed it? 2-in the programming of the AIC we need to initialize the gain and the sampling frequency and the cutoff frequency,and this can be done by using the values of TA and TB calculated before. How to do it?must I respect the succession of the order:xx|TA|00|RA|xx or there is an other way to do it? best regards. khmaies |
