I am also trying to initialize the chip for the first time using FPGA(Spartan6).
The first thing i did is to configure CLK_OUT the same as the reference input, CLK_OUT is ok.
Then i tried to configure the BB PLL. I am trying to configure BBPLL to generate 800MHz, such that my ADC_CLK is 25MHz by using 32 divider and the reference frequency is 40MHz. Data_Clk I am expecting is 3.125MHz.
After configuring the chip, I am not getting CLK_OUT and BBPLL is also not getting locked. Can you please help me to overcome this.
Here i attached the register sequence i followed up to BBPLL config.
