Dual, 10-Bit Tx DAC
The dual, 10-bit digital-to-analog converter (Tx DAC)
operates with clock speeds up to 22MHz. The Tx DAC
digital inputs, D0–D9, are multiplexed on a single 10-bit
bus. The voltage reference determines the Tx DAC full-
scale output voltage. See the Reference Configurations
section for details on setting the reference voltage.
The Tx DAC outputs at IDN, IDP and QDN, QDP are
biased at a 0.9V to 1.35V adjustable DC common-
mode bias and designed to drive a differential input
stage with
≥ 70k input impedance. This simplifies the
analog interface between RF quadrature upconverters
and the MAX19706. Many RF upconverters require a
0.9V to 1.35V common-mode bias. The Tx DAC DC
common-mode bias eliminates discrete level-setting
resistors and code-generated level shifting while pre-
serving the full dynamic range of each Tx DAC. The Tx
DAC differential analog outputs cannot be used in sin-
gle-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.
