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-µm 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-µm 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 power management techniques combine to achieve robust and low-power operation over the existing Category 5 twisted-pair wiring. The BCM5464SR architecture not only meets the requirements of IEEE’s 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 key to implementing high-density Gigabit switches, and the BCM5464SR has the lowest power in the industry at less than 750 mW per port. In addition, the BCM5464SR has extremely low EMI emissions, which reduces the design constraints required to meet EMI radiation specifications. older technologies without having to redesign or requalify a new part. The BCM5464SR supports RGMII, SGMII, and SerDes MAC interfaces. A unique feature of the BCM5464SR is its ability to support both copper and fiber networks, with an integrated SerDes PHY interface that can connect directly to a fiber-optic module. Switching between copper and fiber media can be accomplished either automatically or through software control. The BCM5464SR monitors copper link and fiber signal detect The BCM5464SR also has ESD tolerance well above typical industry standards. This prevents ESD damage not only during manufacturing but during CESD events in the field. The CESD is an ESD event that occurs when an electrically charged network cable is plugged into a network port, which is an issue becoming more prevalent with recent cable installations. The BCM5464 can tolerate over 4 kV of CESD. Each port of the BCM5464SR is fully independent and has individual interface, control and status registers, and incorporates a number of advanced features. A link quality indicator LED gives installers an instant visual indication if there are any problems with the wiring plant supporting operation at the preferred speed. This includes physical wiring defects that the BCM5464SR cannot automatically correct for, channel conditions such as excessive cable length and return loss, crosstalk, echo, and noise. Broadcom’s cable analyzer software can be used with the device to provide remote management of the cable and a first level of diagnostics and fault isolation.
