QUAD XAUI™/CX4/LX4 1.0–3.2-GBPS RETIMER/SWITCH
FEATURES
SUMMARY OF BENEFITS
•
Eight independent retimer channels supporting multiple data
rates from 1.0 to 3.2 Gbps, including 1.06 Gbps, 1.25 Gbps,
2.12 Gbps, 2.488 Gbps, 2.5 Gbps, 2.667 Gbps, 3.125 Gbps, and
3.1875 Gbps
Multiconfigurable to support various operating modes
•
Eight independent 1.0- to 3.2-Gbps retiming channels (single
clock domain)
•
Dual XAUI™/CX4/LX4 to XAUI/CX4/LX4 retiming
channels with redundancy compatible to IEEE802.3™ae
•
Dual XAUI/CX4/LX4 to XAUI/CX4/LX4 retiming switch
Low power dissipation
•
Less than 400 mW per retiming/switch channel including I/O
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, BIST, 10G BERT, and random Ethernet packet
generation
Compact 23-mm × 23-mm package with no external
components required
•
No requirement for heat sink or airflow
•
One device supports a variety of applications including Gigabit
Ethernet, 1× and 2× Fibre Channel, OC-48 SONET (with/without
FEC), InfiniBand
®
, 10-GbE, 10-Gigabit Fibre Channel, or others.
•
•
Flexible architecture supports programmable configurations
enabling an aggregate usable data rate of over 40 Mbps. Built-in
redundancy mode provides high availability to support critical line
side or backplane applications. The high-speed to high-speed
retimer mode extends the use of longer traces on line-card designs.
•
Advanced 0.13µ CMOS process technology provides unparalleled
performance while achieving the lowest possible power
consumption.
•
•
•
Eases linecard designs to allow for multiple connectors or low-cost
PCB materials such as FR4.
•
Drive PMD devices or backplane directly with no external cleanup
circuit required.
•
•
•
Simplifies manufacturability with integrated built-in self-test
(BIST), full loopbacks, and programmable PRBS generator/
checker.
•
Decreases complexity and reduces board space on multichannel
linecard designs.
APPLICATIONS
•
1-GbE and 10-GbE LAN, MAN, WAN switches and routers
•
1×, 2×, or 10-Gigabit Fibre Channel, InfiniBand, SONET network cards
•
40-Gbps backplanes and backplane extenders
•
Advanced test equipment (ATE)
