hello !

I am working ad9361 with a 50MHz ref_clk,When I configure the transmitting Lo at the ingeger times of ref_clk such as 3.9GHz,the spurs is very low.But when I configure the Lo near the ngeger times of ref_clk such as 3.9001GHz,there will be much fraction boundary spurs such as 100KHz,200KHz,300KHz.they are about 40 dB lower than the Lo.I want to know is it a right result.

 

thanks !
