can be large enough to degrade the eye opening at the receiver beyond
what is allowed in the specification. To reduce some of these effects, both
transmitter equalization and receiver pre-emphasis can be used.
Driver Characteristics
Refer to IEEE 802.3ae Clause 47.3.3 for XAUI characteristics and
OIF-CEI-02.0 Clause 6.4.1 for CIE characteristics.
Table 2–2 describes the
characteristics for other possible frequencies.
Receiver Characteristics
Refer to IEEE 802.3ae Clause 47.3.4 for XAUI characteristics and
OIF-CEI-02.0 Clause 6.4.2 for CIE characteristics.
Table 2–3 describes the
characteristics for other possible frequencies.
