  XAUI: Curing Internal Speed Blockages   (Site not responding. Last check: 2007-11-03)
XAUI was originally conceived as a chip-to-chip connection scheme for use on PCBs.
After using XAUI to connect chips to chips and boards to boards, the next logical place for developers to apply this technology is to connect boxes to boxes.
In the latter case, XAUI is used as the coding sublayer for a coarse wavelength division multiplexed (CWDM) fiber-optic PHY.

 XAUI - Wikipedia, the free encyclopedia
XAUI (a concatenation of the Roman numeral X, meaning ten, and the initials of "Attachment Unit Interface") is a standard for connecting 10 Gigabit Ethernet (10GbE) ports to each other and to other electronic devices on a printed circuit board.
For example, a network switch may have many 10GbE ports, perhaps of different types, but must have the capability to connect any port to any other port.
If all these ports are XAUI types, then the same electronic switches can be used to interconnect any of the ports using a minimum number of circuit wires.

 MoreThanIP PRODUCTS/10G XAUI   (Site not responding. Last check: 2007-11-03)
XAUI (10 Gigabit Attachment Unit Interface) provides a low pin count board level interface to connect a 10 Gigabit Ethernet MAC to a physical device such as an optical or a Xenpack, XPAK or X2 modules.
Using a XAUI interface (rather than XGMII) on a 10 Gigabit MAC application simplifies the board design as the discrete Quad SERDES (Serializer/Deserializer) can typically be removed from the board, and as a XAUI interface implements 16 differential PCML (Pseudo Common Mode Logic) signals versus 72 HSTL Class I signals of a XGMII interface.
MorethanIP XAUI Cores can already be used for 10 Gigabit applications design, which provide significant time-to-market advantage, and, through a strong technical partnership with Altera, MorethanIP is able to provide verified solutions to ensure design success.

 i/oZONE Product Review: Texas Instruments TLK3118 Quad XAUI Backplane SerDes
Manufactured in TI's advanced 130nm CMOS technology, the TLK3118 is a flexible, redundant XAUI serial transceiver compliant with the IEEE 802.3ae specification for 10 Gigabit Ethernet.
They have taken a conscientious and solid approach to the challenges of shipping 3+ Gbit/s across the often-hostile environments found in backplanes, with a programmable analog equalizer on the receiver and a programmable pre-emphasis circuit on driver side.
So far, TI has found the fastest slew rate almost always works best, but I'm willing to wager that somebody out there will be able to use a slower rise time to their advantage.
