TDC1000-GASEVM: AVDD vs V3p3

Part Number: TDC1000-GASEVM

Good day,

We have managed to design a working proof of concept using the TDC1000 GASEVM evaluation kit, and we now wish to design our own PCB.

I see on the schematic that there are two separate supply lines, AVDD and V3p3 which are produced from two separate LDO's. Is there a specific reason for this arrangement, and would it be possible to power the TDC1000, TDC7200 and BSTEVM circuitry from one 3.3V line, without significantly affecting the performance?
