The BCM5464SR is optimized for low-power and small footprint PHY family, joining the BCM5404, BCM5414, BCM5421, BCM5421S, size to enable high port density applications. The BCM5464SR enables a BCM5424, and BCM5434. The 0.13-m process is the optimal process that new class of cost effective Gigabit Ethernet equipment by lowering system offers the best performance, lowest cost, and lowest power for Gigabit cost and reducing power dissipation by nearly 25%, driving the delivery of copper solutions. Devices based on the 0.13-m process offer an excellent Gigabit bandwidth to the desktop. long term cost curve, enabling better cost reduction over time compared to The BCM5464SR digital signal processor based architecture and advanced older technologies without having to redesign or requalify a new part. power management techniques combine to achieve robust and low-power Each port of the BCM5464SR is fully independent and has individual operation over the existing Category 5 twisted-pair wiring. The interface, control and status registers, and incorporates a number of BCM5464SR architecture not only meets the requirements of IEEEs advanced features. A link quality indicator LED gives installers an instant 802.3, 802.3u, and 802.3ab, but maintains the industrys highest level of visual indication if there are any problems with the wiring plant supporting margin over IEEE requirements for echo, NEXT, and FEXT. Low-power operation at the preferred speed. This includes physical wiring defects that is key to implementing high-density Gigabit switches, and the the BCM5464SR cannot automatically correct for, channel conditions such BCM5464SR has the lowest power in the industry at less than 750 mW per as excessive cable length and return loss, crosstalk, echo, and noise. port. In addition, the BCM5464SR has extremely low EMI emissions, Broadcoms cable analyzer software can be used with the device to provide which reduces the design constraints required to meet EMI radiation remote management of the cable and a first level of diagnostics and fault specifications. isolation. The BCM5464SR supports RGMII, SGMII, and SerDes MAC interfaces. The BCM5464SR also has ESD tolerance well above typical industry A unique feature of the BCM5464SR is its ability to support both copper standards. This prevents ESD damage not only during manufacturing but and fiber networks, with an integrated SerDes PHY interface that can during CESD events in the field. The CESD is an ESD event that occurs connect directly to a fiber-optic module. Switching between copper and when an electrically charged network cable is plugged into a network port, fiber media can be accomplished either automatically or through software which is an issue becoming more prevalent with recent cable installations. control. The BCM5464SR monitors copper link and fiber signal detect The BCM5464 can tolerate over 4 kV of CESD.
