| BCM5421S (R) 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER WITH SERDES FEATURES * Fully integrated 10BASE-T/100BASE-TX/1000BASE-T Gigabit Ethernet transceiver with SerDes * MII, GMII, TBI, RGMII, RTBI, SGMII, and MAC SerDes interface options * Line-side copper and fiber interface options SUMMARY OF BENEFITS * Provides triple-speed operation for compatibility with legacy networks. * Simplifies system and board design. * RGMII/RTBI reduces I/O pin requirement over GMII and TBI by more than 50%. * SGMII further reduces the interface to six pins, while the serial * MAC SerDes interface requires only four pins. * Lowers system cost and reduces solution footprint. * Provides interoperability with IEEE standard device operation at 10, 100 and 1000 Mbps at half- and full-duplex. * Requires no airflow or heatsink. * On-chip low voltage regulators * Fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards * 0.13-m CMOS -- low power and cost * Low power * 1W per port * Wake on LAN support * 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, pairskew, and pair polarity * Automatic MDI/MDIX crossover at all speeds * Robust CESD tolerance * 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. * High CESD tolerance prevents equipment damage and return. * Operates with larger packets for wider range of packet protocol support and improved efficiency. * Ease of manufacturing with JTAG support, simplified power supply, and multiple MAC interfaces. * Support for jumbo packets up to 9 KB * IEEE 1149.1 (JTAG) boundary scan * 117-pin BGA and 128-pin MQFP packages 10/100/1000BASE-T GBIC Module 1000BASE-T Gigabit Copper or Fiber Uplink Transformer RJ-45 GBIC Connector SerDes GBIC Module BCM5421S BCM5605 BCM5421S Optical Module Switch/MAC Transformer RJ-45 BCM5228 BCM5228 BCM5228 |
