BCM5402 DUAL-PORT 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER
BCM5402 FEATURES
• Two fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers on a single
monolithic CMOS chip
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
• Low power
• Less than 2W per port
• Advanced power management
• Wake On LAN mode—less than 600 mW per port
• ^{MII, GMII, TBI, RGMII, and RTBI interface options}
• ^{Ethernet@WireSpeedTM 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
• ^{Internal 125-MHz low-jitter clock generation}
• ^{Support for jumbo packets up to 9 KB}
• ^{IEEE 1149.1 (JTAG) boundary scan}
• ^{256-pin TBGA and 260FPBGA}
SUMMARY OF BENEFITS
• Low power dual-port integration enables high port
density switches and dual-port adapter cards.
• Compatible with IEEE standard devices operating at
10, 100, and 1000 Mbps at half- and full-duplex.
• ^{No airflow or heatsink required.}
• ^{Wake on LAN mode for low power PC’99 compliant}
adapters (less than 600 mW per-port).
• RGMII/RTBI reduces I/O pin requirement over GMII
and TBI by more than 50%.
• 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.}
• 125-MHz clock eliminates costly external clocking
circuitry for the MAC/ASIC.
• Operates with larger packets for wider range of packet
protocol support and improved efficiency.
• High density package options without heatsink
requirement provides improved testability.
