BCM5705 fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control physical layer transceiver solution high-performance network applications. BCM5705 combines triple-speed, IEEE 802.3 compliant media access controller (MAC), interface, on-chip buffer memory, integrated physical layer transceiver single device. BCM5705 fabricated lowvoltage 0.13µ CMOS process, providing ultra-low power solution. itself, BCM5705 provides complete single-chip Gigabit Ethernet solution. BCM5705 includes 10/100/1000-Mbps Ethernet with full-/ half-duplex capability speeds. Support following 802.3 functions featured MAC: VLAN tagging Layer priority encoding Link aggregation Full-duplex flow control device provides v2.2 interface integrated on-chip buffer memory stand-alone operation. embedded highperformance processor enables custom frame processing features, including segmentation. transceiver fully compatible with IEEE 802.3 standard auto-negotiation speed. Additionally, several Plug Play
enhancements included make device even more user-friendly. unique integrated cable analyzer feature allows user self-diagnose issues with network cabling that could affect host machine. link quality indicator application give installers instant visual indication problems, which include physical wiring defects channel conditions, such excessive cable length, return loss, crosstalk, echo, noise. Broadcom's remote cable management diagnostics software used with device provide remote management cable first level diagnostics fault isolation. BCM5705 continually monitors various channel conditions. optional wirespeed capability allows BCM5705 force auto-negotiation automatically limited speed that channel reliably support rather than performance equipment.
