Hi All,
I have been struggling with the Analog Devices chip AD9911 for over a
week and still no luck.
The SPI Clk and Data are perfect, all the analog and digital voltages
are set as specified in the data sheet. Here are some of my register
values
CSR - 0x"22"
FR1 - 0x"1800"
FR2 - 0x"0000"
CFR - 0x"000382"
CTW0 - 0x"9810624D"
CPOW0 - 0x"0000"
My target is to generate an ouput frequency of 74.25Mhz with a 25 Mhz
system clock. Am I overlooking something obvious, have you faced
similar issues with this chip. Any help in resolving the problem are
welcome.
Regards
