Advance happy Christmas.


I am using Ad-fmcomss4 board and I con figured chip with Artix board with below condition.

Freq; 400 MHz


And I am sending 100khz tone from DAC and I observed 400.1Mhz signal at output of transmiier. Along with I observed 540khz spurious both sides of carrier with higher amplitude. Could you please let me know how to reduce this spurioua ? Is it because of power supply switching noise or any problem with configuration.
