[FCOMMS4-EBZ] REF_CLOCK and SYNC_IN

Hello all,

 

 I'm currently trying to synchronize the clock of AD9364 embedded on a FCOMMS4 eval board with an external reference.

 

 The reference manual (UG-673, page 83, 84, 85) explains that the ref clock should be provided on the REF_CLOCK pin. Then use SYNC_IN as a trigger.

 

 However, the FCOMMS4 board provides a REF_CLOCK input but no SYNC_IN. This pin is grounded, as can be seen on the schematics.

 

 How do you then trigger the REF_CLOCK?
