Multi-DDS-Board synchronization

I would like to synchronize 2-10 DDSs (AD9838), which mounted on separated PCB-Boards. To do that I have to route them to same Clk Signal.

Is there any elegant solution to transmit a Clk signal (16MHz or 5MHz) over 50cm line (coax cable) from a master board to the DDS-Boards? Do I need a clock buffer?

The clk signals will be generated with a multi output clock generator, so they are absolutely synchronized to each other (at least on the master board). The length of the lines could variate between 10 and 50 cm.


Best regards
