I am looking at trying to lock multiple boards together using a common oscillator.
From looking at the circuit diagram it seems I need to add resistor R151 to output the 30.72 MHz clock
and to remove resistor R158 and add resistor R155 to allow the 30.72 MHz clock to be fed
to IC24 Si5351 then of course I need to reprogram it to use the different input clock frequency.
Unfortunately these resistors are not marked on the silk screen (or I can’t see them).
I am working from a revision 1.4 schematic but have revision 1.4s PCBs.
Any help / comments from the Lime design team would be appreciated
