BCM5241A1KMLGT

10BASE-T/100BASE-TX/100BASE-EFX IEEE 802.3u fast Ethernet transceiver HP auto-MDIX Advanced cable diagnostics (CableChecker™) Robust CESD tolerance Operation from a single 3.3V or 2.5V supply source Unique energy detect circuit Low-power mode Super isolate mode Cable length up to 160 meters MII and 7-wire serial interface Power dissipation: < 170 mW The BCM5241 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 BCM5241 to achieve high interoperability and to exhibit robust performance across voltage (+/-10%), temperature, and process variations. The BCM5241 includes features that simplify the installation and maintenance of local area networks. The BCM5241 has an extremely low power dissipation of less than 170 mW. It features an integrated voltage regulator, and can be supplied by either 2.5V or 3.3V power sources. The BCM5241 employs several intelligent power-down states that conserve power, while allowing BCM5241-based products to automatically turn on when needed. The BCM5241 includes a unique Intelligent Power-Management feature that powers down the device if energy is not detected on the cable. This feature is especially useful for portable and power-sensitive applications.
