Table 2. Tx DAC Output Voltage vs. Input Codes
(Internal Reference Mode VREFDAC = 1.024V, External Reference Mode VREFDAC = VREFIN, VFS = 400 for 800mVP-P
Full Scale)
The Tx DAC (IDN, IDP, QDN, QDP) are biased at an
adjustable common-mode DC level and designed to
drive a differential input stage with ≥ 70k
Ω input imped-
ance. This simplifies the analog interface between RF
quadrature upconverters and the MAX19712. Many RF
upconverters require a 0.89V to 1.36V common-mode
bias. The MAX19712 common-mode DC bias eliminates
discrete level-setting resistors and code-generated level
shifting while preserving the full dynamic range of each
Tx DAC. The Tx DAC differential analog outputs can-
not be used in single-ended mode because of the
internally generated common-mode DC level. Table 2
shows the Tx DAC output voltage vs. input codes. Table
10 shows the selection of DC common-mode levels.
See Figure 4 for an illustration of the Tx DAC analog
output levels.
The Tx DAC also features independent DC offset trim on
each ID–QD channel. This feature is configured through
the SPI interface. The DC offset correction is used to opti-
mize sideband and carrier suppression in the Tx signal
path (see Table 9).
