The BCM5464R is optimized for low-power and small footprint PHY family, joining more than a dozen other quad-port and single-port size to enable high port density applications. The BCM5464R enables a PHY products. The 0.13-m process is the optimal process that offers the new class of cost-effective Gigabit Ethernet equipment by lowering system best performance, lowest cost, and lowest power for Gigabit copper cost and reducing power dissipation by nearly 25%, driving the delivery of solutions. Devices based on the 0.13-m process offer an excellent long- Gigabit bandwidth to the desktop. term cost curve, enabling better cost reduction over time compared to older The BCM5464Rs digital signal processor-based architecture and technologies without requiring the redesign or requalification of a new part. advanced power management techniques combine to achieve robust and Each BCM5464R port is fully independent and has individual interface, low-power operation over the existing Category 5 twisted-pair wiring. The control, and status registers, and incorporates a number of advanced BCM5464R architecture not only meets the requirements of IEEEs 802.3, features. A link-quality indicator LED gives installers an instant visual 802.3u, and 802.3ab standards, but maintains the industrys highest level of indication if there are any problems with the wiring plant supporting margin over IEEE requirements for echo, NEXT, and FEXT. Low power is operation at the preferred speed. This includes physical wiring defects that key to implementing high-density Gigabit switches, and the BCM5464R the BCM5464R cannot automatically correct. This includes channel has the lowest power in the industry at 750 mW per port. In addition, the conditions such as excessive cable length and return loss, crosstalk, echo, BCM5464R has extremely low EMI emissions, which reduces the design and noise. Broadcoms cable analyzer software can be used with the device constraints required to meet EMI radiation specifications. to provide remote management of the cable and a first level of diagnostics The BCM5464R supports the RGMII, SGMII, and SerDes MAC and fault isolation. interfaces. The RGMII, SGMII, and Serial SerDes are reduced pin count The BCM5464R also has ESD tolerance well above typical industry (12, 6, and 4, respectively, versus 25) versions of the GMII. The RGMII standards. This prevents ESD damage not only during manufacturing but clock timing can be adjusted to eliminate the board trace delays required by during CESD events in the field. The CESD is an ESD event that occurs the RGMII specification. These reduced pin count interfaces simplify when an electrically-charged network cable is plugged into a network port. design and lower system cost by reducing the number of layers required to This issue is becoming more prevalent with contemporary cable route high-density solutions. In addition, these interfaces allow fewer pins installations. The BCM5464R tolerates over 4 kV of CESD.
