The BCM54610 is optimized for low power and small footprint size to enable uplink and general GbE connectivity applications. By lowering system cost and reducing power dissipation, the BCM54610 enables a new class of cost-effective GbE equipment, driving the delivery of Gigabit bandwidth to the desktop.The BCM54610 digital signal processor-based architecture and advanced power management techniques combine to achieve robust and low power operation over the existing CAT-5 twisted-pair wiring. The BCM54610 architecture also meets the requirements of 802.3, 802.3u, and 802.3ab, but maintains the industry’s highest level of margin over IEEE requirements for Echo, NEXT, and FEXT. Low power is a key factor in implementing Gigabit small form factor NICs and uplinks, and, at less than 500 mW per port, the BCM54610 has the industry's lowest power. Additionally, the BCM54610 has extremely low EMI emissions, which reduces the design constraints required to meet EMI emissions specifications.The BCM54610 supports the IEEE 802.3 standard Reduced Gigabit Media Independent Interface (RGMII). RGMII is a reduced pin-count (12 versus 25) version of the Gigabit Media Independent Interface (GMII). The small package, multiple MAC interfaces, and streamlined power supply lower system cost and simplify the system and board level design.This device is another member of the Broadcom 65-nm Gigabit copper PHY family, joining the BCM54680. The optimal 65-nm process offers the best performance, lowest cost, and lowest power for Gigabit copper solutions. Further, devices based on the 65-nm process offer an excellent 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 incorporates a variety of advanced features. The link quality indicator LED provides installers with immediate visual notification of any problems with the wiring plant supporting operation at the desired speed. This includes physical wiring defects that the BCM54610 cannot automatically correct and channel conditions such as excessive cable length and return loss, crosstalk echo and noise.
