• 1-Gbps lineside SerDes with RGMII MAC interface option
• Fully compliant with IEEE 802.3, IEEE 802.3u, and
IEEE 802.3ab standards
• 0.13-micron CMOS—low power and cost
• Supports copper or fiber in RGMII mode
• Low power
• <625 mW per port
• Advanced power management
• Trace-matched output impedance
• Lineside loopback
• Low EMI emissions
• CableChecker™ diagnostics
• CableChecker detection of 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: 484-pin PBGA
• Low-power, octal-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 with the PHY
• Provides compatibility with IEEE standard devices operating
at 10, 100, and 1000 Mbps at half-duplex and full-duplex
• Lowers system BOM cost and simplifies system design
• Eases system level debug
• Enables use of low-cost magnetics, even in high-density (48+)
designs
• CableChecker characterizes cable plant condition and
immediately indicates cabling issues
• Prevents erroneous equipment return due to bad cable plants
• Prevents manufacturing fallout due to bad cable plants
• Over 3 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
