BCM54616S 10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER FEATURES SUMMARY OF BENEFITS Single-chip integrated triple-speed Ethernet transceiver. Simplifies system and board design. Support for the following copper line interfaces: - Reduced I/O pin requirements with RGMII (over 50%). - 1000BASE-T IEEE 802.3ab - On-chip RGMII timing delay - 100BASE-TX IEEE 802.3u - 100BASE-FX Provides interoperability with IEEE standard devices - 10BASE-T IEEE 802.3 operating at 10 Mbps, 100 Mbps, and 1000 Mbps at half- and full-duplex. RGMII and SGMII MAC interface options Lowers system Bill of Materials (BOM) cost and simplifies Integrated voltage regulator system design. Low power Eases system level debug. - Less than 600 mW per port - Advanced power management Reduces system design constraints to meet EMI emissions standards. Trace-matched output impedance Cable diagnostic function characterizes cable plant condition Lineside loopback and immediately indicates cabling issues. - Prevents erroneous equipment return due to bad cable Low Electromagnetic Interference (EMI) emissions plants. - Prevents manufacturing fallout due to bad cable plants. Cable plant diagnostics - Cable plant analyzer function detects cable plant impairments High CESD tolerance prevents equipment damage and - Link quality indication LED return. - Automatic detection and correction of wiring pair swaps, pair skew, and pair polarity Operates with larger packets for wider range of packet - Automatic MDI/MDIX crossover at all speeds protocol support and improved efficiency. Robust Cable Electrostatic Discharge (CESD) tolerance Ease of manufacturing with JTAG support, simplified power Support for jumbo packets up to 10 KB supply, and multiple MAC interfaces.

The crosstalk cancelers, and all other required support circuitry. The device performs all of the Physical Layer (PHY) functions for BCM54616S is designed to be fully compliant with RGMII, SGMII, and 1000BASE-T, 100BASE-TX, and 10BASE-T on standard Category 5 MII interface specifications, allowing compatibility with industry- UTP cable. The 10BASE-T Ethernet can also run on standard categories standard Ethernet MACs and switch controllers. 3, 4, and 5 UTP. The BCM54616S is designed to comply with the SGMII Designed for reliable operation over worst-case Category 5 cable plants, industry standard and to exceed IEEE specifications for noise the BCM54616S automatically negotiates with its link partner to cancellation and transmission jitter, providing consistent and reliable determine the highest possible operating speed. The device detects and operation over the broadest range of existing cable plants. corrects most common wiring problems. The BCM54616S features The BCM54616S is based on the proven digital-signal processor CableChecker diagnostics, which detects common cable problems, technology of Broadcom, combining digital adaptive equalizers, ADCs, including shorts, opens, and cable length.
