The mixer layout and pin placement has been optimized for high mixer-to-mixer isolation of typically 60dB. The mixers can be
set up to operate in half-duplex mode (1 mixer active) or full duplex mode (both mixers active). The mode selection is done via
hardware control of the MODE pin and by setting the FULLD bit in the CFG1 register as shown in the table below. When in full-
duplex mode, one can either use PLL register bank 1 or 2, the LO signal is routed to both mixers.
