BCM5421 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER
BCM5421 FEATURES
• Fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceiver
• ^{On-chip low-voltage regulators}
• ^{Fully compliant with IEEE 802.3, 802.3u, and 802.3ab}
standards
• ^{0.13um CMOS — low-power and cost}
• ^{Low power}
• 1W per port
• Wake on LAN support
• 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}
• ^{MII, GMII, TBI, RGMII, and RTBI interface options}
• ^{117 BGA and 128 MQFP}
SUMMARY OF BENEFITS
• Provides interoperability with IEEE standard devices
operating at 10, 100, and 1000 Mbps at half- and full-
duplex.
• ^{Lowers system cost and reduces solution footprint.}
• ^{Requires no airflow or heatsink.}
• ^{Provides compliance with PCI 2.2 and PC99/PC2000.}
• ^{Reduces system design constraints to meet EMI}
emissions standards.
• 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.
• Simplifies system and board design.
• ^{RGMII/RTBI reduces I/O pin requirement over GMII and TBI}
by more than 50%.
