In the HMC6350 eval motherboard schematic, there is a net connected to the RX header named "RX_VDD_PLL." This is fed by a 1.3V ADP7118 regulator. However, in the data sheet for the HMC6301, on page 22 showing the eval board, the corresponding header pin is a NC. Is there any reason for this mismatch? Below are both sides to this board to board connection.
