I want to drive the baseband inputs of the ADL5375 from a DAC who's output has to be biased up to 3.3V (AVDD). Figure 62 on page 4 shows a passive level shifting network for going from a DC bias of 500mV to 1500mV. Would I use a similar circuit to level shift from 3.3V down to 1.5V? Can someone post the design equations for this circuit? I could probably figure them out myself, but it would easier/faster if someone had them available.
