By lowering system cost and This device is another member of Broadcom s 0.13 Gigabit copper PHY reducing power dissipation by nearly 30%, the BCM5461S enables a new family, joining the BCM5404, BCM5414, BCM5421, BCM5421S, class of cost-effective Gigabit Ethernet equipment, driving the delivery of BCM5424, BCM5434, BCM5464, and BCM5464S. The 0.13m process is Gigabit bandwidth to the desktop. the optimal process that offers the best performance, lowest cost, and The BCM5461Ss Digital Signal Processor based architecture and lowest power for Gigabit copper solutions. Further, devices based on the advanced power management techniques combine to achieve robust and 0.13 process offer an excellent long-term cost curve, enabling better cost low-power operation over the existing CAT 5 twisted-pair wiring. The reduction over time compared to older technologies, without having to BCM5461S architecture also meets the requirements of 802.3, 802.3u, and redesign or requalify a new part. 802.3ab, but maintains the industrys highest level of margin over IEEE The BCM5461S incorporates a number of advanced features. A link requirements for Echo, NEXT, and FEXT. Low power is a key factor in quality indicator LED provides instant notification of any problems with implementing Gigabit small form factor NICs and uplinks and, at less than the wiring plant operating at the desired speed. This includes physical 700 mW per port, the BCM5461S has the industry s lowest power wiring defects that the BCM5461S cannot automatically correct and requirement. For NIC applications, support for Wake on LAN enables channel conditions such as excessive cable length, and return loss, compliance with PCI 2.2 and PC99/PC2000. Also, the BCM5461S has crosstalk, echo, and noise. Broadcoms cable analyzer software can be used extremely low EMI emissions, which reduces the design constraints with the device to provide remote management of the cable and a first level required to meet EMI emission specifications. of diagnostics and fault isolation. The BCM5461S supports GMII, RGMII, SGMII, SerDes, TBI, RTBI, and The BCM5461S also has ESD tolerance that exceeds typical industry MII MAC interfaces. A unique feature of the BCM5461S is its ability to standards. This prevents ESD damage during manufacturing and during support both copper and fiber networks, with an integrated SerDes PHY CESD events in the field. Cable-sourced electrostatic discharge (CESD) is interface that can connect directly to a fiber-optic module. Switching an ESD event that occurs when an electrically charged network cable is between copper and fiber media can be accomplished either automatically plugged into a network port, an issue becoming more prevalent with or through software control.
