LO Phase adjust values in register 0x05 in ADMV1014

.I just wanted to know about the Phase offset settings in the LO path. The ACE software doesn’t have any provision to set these values through block diagram, but the register 0x05 has been set at reset to 0x20 and 0x40 . Will this have effect on my LO signal path? What is the ideal value to be set in these registers if I don’t want to have any phase adjustment. I also wanted to know about giving the VCTRL externally. There is a capacitor C13 in the line of VCTRL. So, how do I give the DC voltage through the external pin. Kindly clarify my above mentioned queries.
