MAGNETICS SELECTION GUIDE
The NetPHY-1 device requires a 1:1 ratio for both the
receive and the transmit transformers. Refer to Table 2
for transformer requirements. Transformers meeting
these requirements are available from a variety of mag-
netic 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.
Table 2.
Transformer Requirements
CRYSTAL SELECTION GUIDE
A crystal can be used to generate the 25 MHz refer-
ence clock instead of a crystal oscillator. An M-TRON
crystal, part number is 00301-00169, MP-1 Fund, @
25.000000 MHz, ±50 ppm or equivalent may be used.
The crystal must be a fundamental type, parallel res-
onant. Connect to X1 and X2, shunt each crystal lead
to ground with an 18pf capacitor (see Figure 16).
