Brief
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 modeâless 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 PCâ99 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.
