11.7 Magnetic Selection Guide
Refer to Table 2 for transformer requirements.
Transformers, meeting these requirements, are
available from a variety of magnetic manufacturers.
Designers should test and qualify all magnetic before
using them in an application. The transformers listed
in Table 2 are electrical equivalents, but may not be
11.8 Crystal Selection Guide
A crystal can be used to generate the 25MHz
reference clock instead of an oscillator. The crystal
must be a fundamental type, and series-resonant.
