The lowest-power Fast Ethernet PHY. It features an integrated voltage BCM5221 has been designed and tested to withstand over 5 KV of regulator, and can be supplied by either a 2.5V or 3.3V power source. In CESD which, unlike other transceivers, prevents the device from being addition, the BCM5221 has several intelligent power-down states that destroyed in a CESD event. conserve power, yet allow products based on it to automatically turn on when needed. DSP-Based PHY Technology The BCM5221 includes a unique Intelligent Power-Management feature The BCM5221 builds on Broadcom s proven DSP PHY design and full that powers down the device if energy is not detected on the cable. This custom circuit design techniques to create a highly integrated and robust feature is especially useful for portable and power-sensitive applications physical layer solution. DSP techniques allow the BCM5221 to achieve such as laptop LAN card adapters. The BCM5221 allows PCMCIA or high interoperability and to exhibit robust performance across voltage CardBus adapters to remain plugged in and draw virtually no energy (10%), temperature (40C to 85C), and process variations. even if the client is no longer connected to the network. Because most Broadcom s DSP-based, Digi- technology has been proven in the laptop users do not remove their LAN PC card when working remotely, shipment of over two billion Fast Ethernet ports. Broadcom s superior this feature results in a noticeably extended battery life for laptop quality has resulted in a failure rate well under 10 PPM. computer users. The BCM5221 can be set to periodically wake up at a user-defined Applications interval, allowing the product to initiate keep-alive traffic on the Applications for the BCM5221 that take advantage of its low power and network. For lowest power consumption, the BCM5221 can be put in a high network tolerance: power-off state (<2.5 mW). Servers - Network Controller - Sideband Cable modems Network Tolerance Interface (NC-SI) using RMII interface The BCM5221 includes features that simplify the installation and Digital TV Set-Top boxes maintenance of local area networks. One such feature is the HP Auto- PCMCIA/CardBus cards Print servers MDIX capability, which automatically detects and corrects crossed LAN on motherboard (LOM) Wireless Access Points (WAP) cables. With HP Auto-MDIX, the installer does not need to know what IP phones Embedded telecom is on the other end of the network cable: the BCM5221 automatically switches its transmit and receive circuitry to accommodate the link partners polarity.
