AD9371 Tx and Rx LOs not locked

Question

Hi all, 
 I want to adjust both LOs (Tx and Rx) at the same time and guarantee that the LOs are phase locked (or at least the phase difference between the two is constant). Is there any option to control the Tx and Rx to use either the same LO or the same reference for the LO?? But I assumed that Tx LO and the ORx LO internally phase locked ?? 
 
 Thank you

Same internal LO cannot be used for Tx and Rx. The phase are not aligned and you need to do external calibration to calibrate out the phase difference.)
