PRELIMINARY DATA SHEET
10/100BASE-TX/FX Mini-Φ™ Transceiver
GENERAL DESCRIPTION
The BCM5221 is a single channel, low-power, 10/100BASE-TX/FX transceiver targeting a number of applications requiring intelligent power management and robust network tolerance. The BCM5221 operates at 3.3V or 2.5V. The devices contain a full-duplex 10BASET/100BASE-TX/100BASE-FX Fast Ethernet transceiver, which performs all of the physical layer interface functions for 10BASE-T Ethernet on CAT 3, 4, and 5 unshielded twisted pair (UTP) cable and 100BASE-TX Fast Ethernet on CAT 5 UTP cable. In addition, layout patibility with the previous generation BCM5201 shortens the design cycle for the BCM5221....
