10.14.2 DC interface to an Analog Quadrature Modulator (AQM)
The DAC1405D750 differential outputs can operate up to 2 V
is recommended to connect the center tap of the transformer to a 62  resistor connected
to the 3.3 V analog power supply, in order to adjust the DC common mode to
approximately 2.7 V (see
When the system operation requires to keep the DC component of the spectrum, the
DAC1405D750 can use a DC interface to connect to an AQM. In this case, the offset
compensation for LO cancellation can be made with the use of the digital offset control in
the DAC.
