the application note for narrowband optimum component values.
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.
