FD Mode
The MAX19712 features an FD mode, which is ideal for
applications supporting frequency-division duplex. In
FD mode, both Rx ADC and Tx DAC, as well as their
respective digital buses, are active and the device can
receive and transmit simultaneously. Switching from FD
mode to other Rx or Tx modes is fast (0.1s) since
