Typical Interface Circuit
Very few external components are required to achieve
the stated device performance. Figure 3 shows the typical
interface requirements when using the CDK1300 in nor-
mal circuit operation. The following sections provide
descriptions of the major functions and outline performance
criteria to consider for achieving the optimal device
performance.

Analog Input
The input of the CDK1300 can be configured in various
ways depending on whether a single-ended or differential
input is desired.
The AC-coupled input is most conveniently implemented
using a transformer with a center-tapped secondary winding.
The center tap is connected to the V
