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 PC
