MEDIA INTERFACE
FEATURES
SUMMARY OF BENEFITS
• Four fully integrated 10BASE-T/100BASE-TX/1000BASE-T Gigabit
Ethernet transceivers
• RGMII, SGMII, and SerDes MAC interface options
• Copper or SerDes line interface options
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards
0.13-micron CMOS—low-power and cost
• 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: 256-pin BGA
• 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
• Flexibility for copper or fiber applications
• Provides compatibility with IEEE standard devices operating at 10,
100, and 1000 Mbps at half-duplex and full-duplex
• Requires no air flow or heat sink
• 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
