By lowering PHY family, joining the BCM54680. The optimal 65-nm process offers system cost and reducing power dissipation, the BCM54610 enables a the best performance, lowest cost, and lowest power for Gigabit copper new class of cost-effective GbE equipment, driving the delivery of solutions. Further, devices based on the 65-nm process offer an excellent Gigabit bandwidth to the desktop. long-term cost curve, enabling better cost reduction over time compared to older technologies, without having to redesign or requalify a new part. The BCM54610 digital signal processor-based architecture and advanced power management techniques combine to achieve robust and The BCM54610 incorporates a variety of advanced features. The link low power operation over the existing CAT-5 twisted-pair wiring. The quality indicator LED provides installers with immediate visual BCM54610 architecture also meets the requirements of 802.3, 802.3u, notification of any problems with the wiring plant supporting operation and 802.3ab, but maintains the industrys highest level of margin over at the desired speed. This includes physical wiring defects that the IEEE requirements for Echo, NEXT, and FEXT. Low power is a key BCM54610 cannot automatically correct and channel conditions such as factor in implementing Gigabit small form factor NICs and uplinks, and, excessive cable length and return loss, crosstalk, echo, and noise. at less than 500 mW per port, the BCM54610 has the industry s lowest Broadcom cable analyzer software can be used with the device to power. Additionally, the BCM54610 has extremely low EMI emissions, provide remote management of the cable and first-level diagnostics and which reduces the design constraints required to meet EMI emissions fault isolation. specifications. The BCM54610 also has ESD tolerance that exceeds typical industry The BCM54610 supports the IEEE 802.3 standard Reduced Gigabit standards. This feature not only prevents ESD damage during Media Independent Interface (RGMII). RGMII is a reduced pin-count manufacturing but also during cable-sourced electrostatic discharge (12 versus 25) version of the Gigabit Media Independent Interface (CESD) events in the field. CESD is an ESD event that occurs when an (GMII). The small package, multiple MAC interfaces, and streamlined electrically charged network cable is plugged into a network port, an power supply lower system cost and simplify the system and board level issue becoming more prevalent with contemporary cable installations. design.
