4-PORT GIGABIT COPPER TRANSCEIVER WITH SGMII & SERDES MAC INTERFACE
BCM5434 FEATURES
• Four fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers
• SGMII and SerDes MAC Interface options
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
• 0.13 um CMOS — low power and cost
• Low power
• 1W per port
• Advanced power management
• Low EMI emissions
• Ethernet@WireSpeedTM logic automatically selects the
maximum speed based on channel conditions
• 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 CESD tolerance
• Support for jumbo packets up to 9 KB
• IEEE 1149.1 (JTAG) boundary scan
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
• SGMII interface reduces I/O pin requirement over RGMII by
more than 50%.
• 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 half- and full-
duplex.
• Requires no airflow or heatsink.
• Reduces design constraints in high-density
• applications that have higher EMI emissions.
Automatically configures the link to support the
highest possible speed based on link partner capability
• and characteristics of the channel.
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.
High 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.
