Hi every body,
I have some problem to generate an output on ad9914 controlled through FPGA. In fact after configured the internal control register CFR, and write value of FTW,AMP and POW in profile 0, i do not have the same value in output.
For example: i write 0x0A101250 in FTW ; 0x402 in AMP and 0x1250 in POW to generate 98.26Mhz
At the output i have 271,41Mhz
I don't understand why?
Even when i change the frequency, the output change also not the same frequency .
I hope someone can help me
