Table 2. Tx Path Output Voltage vs. Input Codes
(Internal Reference Mode VREFDAC = 1.024V, External Reference Mode VREFDAC = VREFIN, VFS = 410 for 820mVP-P
Full Scale and VFS = 500 for 1VP-P Full Scale)
tial input stage with
≥ 70kΩ input impedance. This simpli-
fies the analog interface between RF quadrature upcon-
verters and the MAX19711. Many RF upconverters
require a 0.86V to 1.36V common-mode bias. The
MAX19711 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 cannot be
used in single-ended mode because of the internally
generated common-mode DC level. Table 2 shows the
Tx path output voltage vs. input codes. Table 11 shows
the selection of DC common-mode levels. See Figure 5
for an illustration of the Tx DAC analog output levels.
The buffer amplifiers also feature a programmable full-
scale output level of ±410mV or ±500mV and indepen-
dent DC offset trim on each ID–QD channel. Both features
are configured through the SPI interface. The DC offset
correction is used to optimize sideband and carrier sup-
pression in the Tx signal path (see Tables 8 and 10).
