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.
