QUAD-PORT GIGABIT COPPER TRANSCEIVER WITH RGMII AND RTBI INTERFACE
BCM5424 FEATURES
⢠Four fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers
⢠RGMII and RTBI interface options
⢠Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
⢠0.13 um CMOS â 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
⢠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.
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.
Supports jumbo packets for wider range of packet
⢠protocol compatibility.
Ease of manufacturing with JTAG support, simplified
power supply, and multiple MAC interfaces.
