Hi all
I used 4 chips 9244 and 8 chips 7242 for 8 chips DSP6678 on my board. Each 9244 and 2 chips 7244 supply 1 chip DSP6678 CVDD and VCC1V0, and I got some problems.
Each 9244 only have some rails right, and the output voltage of the other rails is zero, eg: only the first rail of one 9244 is right and the other 3 rails output voltage are zero. All the 9244 have the similar condition. And I found if I adjust the frequency from 799kHz to 500kHz the 4th rail turns right, but the 2nd and 3rd stays zero.
The configuration files I have used before , and the 9244 on that board works well. I have changed the 7242 and 9244 on this board, but it dosen't work.1323.XH_9244_Config.xml
This problem has troubled me for almost a month , I dont known what to do. I hope some one can help me, and I will be very appreciated.
