Data Sheet
TRANSMIT DAC OPTIONS
The AD9779 recommended in the previous sections of this data
sheet is by no means the only DAC that can be used to drive the
ADL5372. There are other appropriate DACs, depending on the
level of performance required. Table 6 lists the dual TxDACs
offered by Analog Devices.

All DACs listed have nominal bias levels of 0.5 V and use the
same simple DAC modulator interface that is shown in Figure 32.
