10-GbE XAUI™ TRANSCEIVER WITH HIGH-SPEED REDUNDANCY
FEATURES
• 10-GbE transceiver supporting various operating modes
• IEEE 802.3™ae-compliant XAUI™ to XGMII transceiver
• XAUI-to-XAUI retiming
• Low power dissipation
• Less than 300 mW per transceiver channel including I/O
• SONET/SDH-quality jitter performance
• Less than three picoseconds rms jitter generation
• Exceeds SONET jitter tolerance mask
• High performance programmable receive equalization and
transmit pre-emphasis
• Transmit pre-emphasis for interoperability with CML SerDes
• Receive equalization for copper interconnects
• Enhanced test capability
• Full loopback and on-chip PRBS generator/checker
• IEEE (1149.1) JTAG
• Compact 21-mm × 21-mm BGA package
• No requirement for heat sink or airflow
SUMMARY OF BENEFITS
• _{Advanced 0.13µ CMOS process technology provides}
unparalleled performance while achieving the lowest possible
power consumption
• _{IEEE 802.3ae 10-GbE physical coding sublayer (PCS) has a}
selectable 8B/10B encoding/decoding block on-chip that can
be configured to support the 10-Gbps attachment unit
interface (XAUI)
• _{Superior jitter characteristics enable the serializing/}
deserializing (SerDes) of data signals transmitted through
front panel or backplane networking equipment supporting
both primary and protection circuits
• _{Drive PMD devices or backplane directly with no external}
clean-up circuit required
• _{Simplifies manufacturability with integrated built-in self-test}
(BIST), high-speed and low-speed loopbacks, and
programmable PRBS generator/checker
• _{Decreases complexity and reduces board space on}
multichannel linecard designs

• _{1-GbE and 10-GbE LAN, MAN, WAN switches and routers}
• _{Advanced test equipment (ATE)}
