For applications where SNR is a key parameter, differential
transformer coupling is the recommended input configuration
to achieve the true performance of the AD9639 (see Figure 38
Regardless of the configuration, the value of the shunt capacitor, C,
is dependent on the input frequency and may need to be reduced
or removed.

Single-Ended Input Configuration
A single-ended input may provide adequate performance in
cost-sensitive applications. In this configuration, SFDR and
distortion performance can degrade due to input common-mode
swing mismatch. If the application requires a single-ended input
configuration, ensure that the source impedances on each input
are well matched to achieve the best possible performance. A
full-scale input of 1.25 V p-p can be applied to the VIN + x pin
of the AD9639 while the VIN x pin is terminated. Figure 42
shows a typical single-ended input configuration.
