AD9361 BIST: Are the two channels of Rx PRBS/Tone synchronized?

I am using AD9361 in muliple-channel application where synchronization of the channel is improtant.

 

When I do channel calibration, I found the received data from the two channel sometimes have a delay of 1 sample.  Then, I want to check if my FPGA interface has timing issue. Therefore, I use the BIST fuction to generate data patterns internally from AD9361.

 

I want to confirm that if I set to BIST mode, are the RX data from the two channels synchronized or NOT ?

In other words, Should I expect the same output from the two channels or not?

 

0x3F4—BIST Config is set to 0xC3.
