The four-way multiplexed ADC with magnitude comparator may be used for monitoring RSSI, battery
voltage, temperatures, reflected signals or error voltages.
The three DACs may be used to adjust VCOs, reference oscillators, power output, bias current or IF gain.
The two variable attenuators may be used to adjust deviation, modulation depth or baseband gain.
The FX839 is controlled via the standard serial 'C-BUS'. This is complementary to, and compatible with, many
standard microcomputers and other baseband processing blocks.
