I am intending to use 2x C667x DSP on my boards. The Hardware User Guide shows the schematic for UCD9222, UCD7242 for DSP C6616. I was wondering could I replace the 2x C6616 with my 2x C667x DSP.
I should be using Configuration2 with 1x UCD9222, 2x UCD7242 in order to provide 20A per rail as I use the power estimation excel sheet with C6678 and calculate the CVDD to be 12A for 1x C6678. I believe I am overestimating the current requirement of 12A for 1x C6678 hence the 20A should be sufficient.
Btw, I realize when I switch the power estimation excel sheet from power to current in the variable field, the CVDD1 column does not change. I believe your side may have made an error in doing the macro for the excel sheet.
