BCM5221A4KPT

Product Summary

With a power dissipation of <275 mW, the BCM5221A4KPTG is the industry lowest power Fast Ethernet PHY. It features an integrated voltage regulator, and can be supplied by either a 2.5V or 3.3V power source. The BCM5221A4KPTG incorporates several Intelligent Power Management features, including three low-power modes with varying levels of power dissipation. The device is capable of powering down when not connected to the network, making it ideal for power sensitive applications, such as portable computer LOMs and PCMCIA/CardBus cards. The BCM5221A4KPTG can also be set to periodically power up at user-defined intervals, allowing the system to initiate keep-alive traffic on the network, and can be put in a power-off state. In addition, the BCM5221A4KPTG also incorporates the HP Auto-MDIX feature, which automatically detects and corrects the polarity of crossed cables, resulting in simplified local area network (LAN) installation and maintenance. The BCM5221A4KPTG was designed and tested to withstand over 9kV of cable-sourced electrostatic discharge (CESD), which occurs when an electrically charged network cable is plugged into networking equipment. The CESD performance prevents the system from being destroyed due to this electric discharge during installation and cable insertion.
