BCM5222 - Dual-Port MII 10/100BASE-TX Transceiver

Dual-Port MII 10/100BASE-TX Transceiver

With a power dissipation of less than 195 mW per port, the BCM5222 is the industry's lowest-power Fast Ethernet PHY. 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).
