XAUI Mode
XAUI is an optional, self-managed interface that you can insert between the
reconciliation sublayer and the PHY layer to transparently extend the physical reach
of the XGMII.
XAUI addresses several physical limitations of the XGMII. XGMII signaling is based
on the HSTL Class 1 single-ended I/O standard, which has an electrical distance
limitation of approximately 7 cm. Because XAUI uses a low-voltage differential
signaling method, the electrical limitation is increased to approximately 50 cm.
Another advantage of XAUI is simplification of backplane and board trace routing.
XGMII is composed of 32 transmit channels, 32 receive channels, 1 transmit clock,
1 receive clock, 4 transmitter control characters, and 4 receive control characters for a
74-pin wide interface. XAUI, on the other hand, only consists of 4 differential
transmitter channels and 4 differential receiver channels for a 16-pin wide interface.
This reduction in pin count significantly simplifies the routing process in the layout
design.
