In addition, the BCM5222 has several intelligent power-down states that conserve power, yet allow products based on it to automatically turn on when needed. The BCM5222 includes a unique Intelligent Power-Management feature that powers down the device if energy is not detected on the cable. The energy detect feature is especially useful for portable and power-sensitive applications, as the BCM5222 draws virtually no energy if the cable is not plugged in and the client is not connected to the network. This results in noticeably extended battery life for portable applications, and increases product reliability due to decreased power dissipation. For lowest power consumption, the BCM5222 can be put in a power-off state (<2.0 mW). Network Tolerance The BCM5222 includes features that simplify the installation and maintenance of local area networks. One such feature is the HP Auto-MDIX capability, which automatically detects and corrects crossed cables. With HP Auto-MDIX, the installer does not need to know what is on the other side of the network cable: the BCM5222 automatically switches its transmit and receive circuitry to accommodate the link partner's polarity.

Cable-sourced electrostatic discharge (CESD) is a recently discovered phenomenon that occurs when an electrically charged network cable is plugged into a networked product, an issue becoming more prevalent with recent cable installations. The BCM5222 has been designed and tested to withstand over 9 KV of CESD, which unlike other transceivers, prevents the device from being destroyed in a CESD event. DSP-Based PHY Technology The BCM5222 builds on Broadcom's proven DSP PHY design and full custom circuit design techniques to create a highly integrated and robust physical layer solution. DSP techniques allow the BCM5222 to achieve high interoperability and to exhibit robust performance across temperature (-40 to 85C), voltage, and process variations. Broadcom's DSP-based, DigiPHYTM technology has been proven in the shipment of over 450,000,000 Fast Ethernet ports. Broadcom's superior quality has resulted in a failure rate well under 10 PPM.
