Brief
QUAD-PORT 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER
BCM5464 FEATURES
• Four fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers
• GMII, RGMII, SGMII, and SerDes MAC interface options
• 1-Gbps line-side SerDes with GMII/RGMII MAC interface
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
• 0.13-micron CMOS—low-power and cost
• Supports copper or fiber in GMII and RGMII modes
• Low-power
• 750 mW per port
• Advanced power management
• Trace matched output impedance
• Line-side loopback
• Low EMI emissions
• Cable plant diagnostic
• Cable plant analyzer function detects cable plant impairments
• Link quality indication LED
• Automatic detection and correction of wiring pair swaps, pair
skew, and pair polarity
• Automatic MDI/MDIX crossover at all speeds
• Robust cable-sourced electrostatic discharge (CESD)
tolerance
• Support for jumbo packets up to 10 KB
• IEEE 1149.1 (JTAG) boundary scan
• Package: 354-pin BGA
SUMMARY OF BENEFITS
• Low-power, quad-port integration enables single-row,
high port density switches
• Lowers system costs by eliminating PCB layers required for
routing high density solutions
• Reduced I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%)
• Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification
• Lowers MAC/switch costs by reducing the number of pins
required to interface to the PHY
• Provides compatibility with IEEE standard devices
operating at 10, 100, and 1000 Mbps at at half-duplex
and full-duplex
• Requires no airflow or heatsink
• Lowers system BOM cost and simplifies system design
• Eases system level debug
• Enables use of low cost magnetics, even in high density
(48+) designs
• Cable diagnostic function characterizes cable plant
condition and immediately indicates cabling issues
• Prevents erroneous equipment return due to bad cable plants
• Prevents manufacturing fall-out due to bad cable plants
• Over 4 kV of CESD tolerance prevents equipment
damage and return
• Operates with larger packets for wider range of packet
protocol support and improved efficiency
• Ease of manufacturing with JTAG support, simplified
power supply, and multiple MAC interfaces
