Figure 4 shows a typical wideband (from 0.4 GHz to 4 GHz) application circuit. Refer to

the application note for narrowband optimum component values.

12.1 External DAC interfacing

Nominal DAC single-ended output currents are between 0 mA to 20 mA. When driving

into 25  impedance, this creates 250 mV peak-single signal (1 V (p-p) differential). Half

of the impedance is placed at the DAC outputs as 50  load resistors, the other half is

provided by the modulator itself. In this way, the differential filter can be properly

terminated by 100  at both ends.
