BCM5226
Target usage: Fast Ethernet switches.
Low power < 300 milliwatts per port.
Auto-MDIX detects and corrects cabling errors.
Provides robust performance over a broad range of operating
conditions.
Single-chip device contains six independent Fast Ethernet
transceivers.
Performs all physical layer interface functions for 100BASE-
TX full-duplex or half-duplex Ethernet on Category 5 twisted-
pair cable and 10BASE-T full- or half-duplex Ethernet on
Category 3, 4, or 5 cable.
Permits transmission over fiber-optic cabling when paired
with an external fiber-optic transceiver.
Compliant with IEEE 802.3 standard.
IEEE 1149.1 (JTAG) scan chain support.
