Brief
QUAD-PORT GIGABIT COPPER TRANSCEIVER WITH RGMII AND RTBI INTERFACE
BCM5414 FEATURES
• Four fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers
• ^{RTBI and HSTL level RGMII interface options}
• ^{Fully compliant with IEEE 802.3, 802.3u, and 802.3ab}
standards
• ^{0.13µ 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
• ^{1.5V or 1.8V HSTL signal levels eliminate the need for 3.3V}
power supply, lowering system cost and simplifying design
• ^{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.
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 and
simplified power supply.
