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
