AD9361 2R2T FDD LVDS no rx data if 1 tx channel disabled

We are seeing something strange and wondering if it is expected behaviour.


We are running 2R2T FDD LVDS mode using both RX and TX chains.  If we clear either bit 7 or bit 6 (but not both) of register 0x002 to disable one of the two tx chains, we stop receiving any data on both rx chains.  If we clear both bits 7 and 6 of register 0x002 to turn off both tx chains, then we once again start seeing rx data.


This seems odd to us that the tx channel enables are affecting the rx chains in this manner.  Is this behaviour expected?
