11.8 Magnetics 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 magnetics before
using them in an application. The transformers listed
in Table 2 are electrical equivalent, but may not be
pin-to-pin equivalent.

11.9 Crystal Selection Guide
A crystal can be used to generate the 25Mhz
reference clock instead of a oscillator. The crystal
must be a fundamental type, series-resonant.
Connect to X1 and X2, shunt each crystal lead to
ground with a 22pf capacitor (see figure 7).
