  1. 2007/06/22 BCM8040 - QUAD XAUI™/CX4/LX4 1.0–3.2-GBPS RETIMER/SWITCH
FEATURES
• 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

SUMMARY OF BENEFITS
• 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)
