DAC1205D750
Dual 12-bit DAC, up to 750 Msps; 4x and 8x interpolating
The DAC1205D750 differential outputs can operate up to 2 V
o(p-p)
. In this configuration, it
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
Figure 14
).
10.14.2
DC interface to an Analog Quadrature Modulator (AQM)
When the system operation requires to keep the DC component of the spectrum, the
DAC1205D750 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.
Figure 15
provides an example of a connection to an AQM with a 1.7 V

common-mode input level.
