| BCM5421 PRODUCT (R) Brief OF BENEFITS BCM5421 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER BCM5421 FEATURES SUMMARY Fully integrated 10BASE-T/100BASE-TX/ * 1000BASE-T Gigabit Ethernet transceiver * On-chip low-voltage regulators Fully compliant with IEEE 802.3, 802.3u, and 802.3ab * standards * 0.13um CMOS -- low-power and cost * Low power * 1W per port * Wake on LAN support * Advanced power management TM Provides with devices * operatinginteroperability 1000 IEEE standardand fullat 10, 100, and Mbps at half- * * * * * * * Low EMI emissions * Ethernet@WireSpeed logic automatically selects the maximum speed based on channel conditions * Cable plant diagnostic duplex. Lowers system cost and reduces solution footprint. Requires no airflow or heatsink. Provides compliance with PCI 2.2 and PC99/PC2000. Reduces system design constraints to meet EMI emissions standards. 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. * Robust CESD tolerance * Support for jumbo packets up to 9 KB * IEEE 1149.1 (JTAG) boundary scan * MII, GMII, TBI, RGMII, and RTBI interface options * 117 BGA and 128 MQFP 10/100/1000BASE-T Network Interface Card * 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 High CESD * return. tolerance prevents equipment damage and Operates with larger wider range * protocol support and packets forefficiency. of packet improved Ease of manufacturing with JTAG support, * power supply, and multiple MAC interfaces.simplified * Simplifies system and board design. over GMII and TBI RGMII/RTBI reduces I/O pin requirement * by more than 50%. 1000BASE-T Gigabit Uplink BCM5700 Gigabit PCI MAC BCM5421 Transformer RJ-45 BCM5605 24FE+2G Switch Transformer RJ-45 BCM5421 BCM5421 Transformer BCM5228 Octal 10/100Mbps Phy BCM5228 Octal 10/100Mbps Phy BCM5228 Octal 10/100Mbps Phy RJ-45 |
