Table 8. Qualified Transformer List
Selection of Isolation Transformer(1)
One simple 1:1 isolation transformer is needed at the line interface. An isolation transformer with integrated common-mode
choke is recommended for exceeding FCC requirements. The following table gives recommended transformer characteristics.

Note:
1. The IEEE 802.3u standard for 100BASE-TX assumes a transformer loss of 0.5dB. For the transmit line transformer, insertion loss of up to 1.3dB can
be compensated or by increasing the line drive current by means of reducing the ISET resistor value. Please select the transformer that supports
auto-MDI/MDI-X.
Selection of Reference Crystal
An oscillator or crystal with the following typical characteristics is recommended.
