BCM5414 PRODUCT Brief ® QUAD-PORT GIGABIT COPPER TRANSCEIVER WITH RGMII AND RTBI INTERFACE B C M 5 4 1 4 F E AT U R E S S U M M A R Y 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 logic automatically selects the • Ethernet@WireSpeed maximum speed based on channel conditions • Cable plant diagnostic TM • 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 O F B E N E F I T S 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.
