If the outputs are to be used in single-ended mode, it is recommended that the true and false signals be terminated with a 50Ω
resistor.

Figure 61 on page 55 illustrates the configuration of the dual ADC (1:2 DMUX mode,
independent I and Q clocks) driving an LVDS system (ASIC/FPGA) with potential addi-
tional DMUXes used to halve the speed of the dual ADC outputs.
