TM is a member of Broadcoms QuadSquad family of quad Gigabit This device is another member of Broadcoms 0.13-m Gigabit copper Ethernet PHYs. The BCM5464S is optimized for low-power and small PHY family, joining the BCM5404, BCM5414, BCM5421, BCM5421S, footprint size to enable high port density applications. The BCM5464S BCM5424, and BCM5434. The 0.13-m process is the optimal process enables a new class of cost effective Gigabit Ethernet equipment by that offers the best performance, lowest cost, and lowest power for lowering system cost and reducing power dissipation by nearly 25%, Gigabit copper solutions. Devices based on the 0.13-m process offer an driving the delivery of Gigabit bandwidth to the desktop. excellent long term cost curve, enabling better cost reduction over time The BCM5464S digital signal processor based architecture and compared to older technologies without having to redesign or requalify advanced power management techniques combine to achieve robust and a new part. low-power operation over the existing Category 5 twisted-pair wiring. Each port of the BCM5464S is fully independent and has individual The BCM5464S architecture not only meets the requirements of IEEEs interface, control and status registers, and incorporates a number of 802.3, 802.3u, and 802.3ab, but maintains the industrys highest level of advanced features. A link quality indicator LED gives installers an margin over IEEE requirements for echo, NEXT, and FEXT. Low- instant visual indication if there are any problems with the wiring plant power is key to implementing high-density Gigabit switches, and the supporting operation at the preferred speed. This includes physical BCM5464S has the lowest power in the industry at less than 750 mW per wiring defects that the BCM5464S cannot automatically correct for, port. In addition, the BCM5464S has extremely low EMI emissions, channel conditions such as excessive cable length and return loss, which reduces the design constraints required to meet EMI radiation crosstalk, echo, and noise.

A unique feature of the BCM5464S is its ability to support The BCM5464S also has ESD tolerance well above typical industry both copper and fiber networks, with an integrated SerDes PHY interface standards. This prevents ESD damage not only during manufacturing but that can connect directly to a fiber-optic module. Switching between during CESD events in the field. The CESD is an ESD event that occurs copper and fiber media can be accomplished either automatically or when an electrically charged network cable is plugged into a network through software control. The BCM5464S monitors copper link and port, which is an issue becoming more prevalent with recent cable installations. The BCM5464 can tolerate over 4 kV of CESD.
