For baseband applications where SNR is a key parameter,
differential transformer coupling is the recommended input
configuration. An example is shown in Figure 38. The CML
voltage can be connected to the center tap of the secondary
winding of the transformer to bias the analog input.
The signal characteristics must be considered when selecting a
transformer. Most RF transformers saturate at frequencies
below a few MHz, and excessive signal power can cause core
saturation, which leads to distortion.

At input frequencies in the second Nyquist zone and above, the
noise performance of most amplifiers is not adequate to achieve
the true SNR performance of the AD9233. For applications
where SNR is a key parameter, transformer coupling is the
recommended input. For applications where SFDR is a key
parameter, differential double balun coupling is the recom-
mended input configuration. An example is shown in Figure 39.
As an alternative to using a transformer-coupled input at
frequencies in the second Nyquist zone, the
driver can be used. An example is shown in Figure 40.
In any configuration, the value of the shunt capacitor, C, is
dependent on the input frequency and source impedance
and may need to be reduced or removed. Table 8 displays
recommended values to set the RC network. However, these
values are dependant on the input signal and should only be
used as a starting guide.
