AD9371 phase coherent mode

Working on a design that may need your AD9371 or AD9375 wideband dual channel RF transceivers.

I am focusing on how to get multiple of these transceivers to operate in a phase coherent modes.  Do you have any information (i.e. app-note and/or design documents) that describes how to configure and use these parts in phase coherent modes?  The datasheet eludes to that the LO GENERATOR within the part is capable of INPUT and/or OUTPUT both the RX and TX LO’s.  However, I did not see any detail more than just the external LO has to be twice the frequency of the desired RF signal.  Not to mention on how to synchronize the baseband data between parts.  Is there a signal to synchronize the DSP and as well as ADC sampling?
