10/100BASE-TX/FX HEX-Φ™ TRANSCEIVER

The Broadcom® BCM5226 is a single-chip device containing six independent Fast Ethernet transceivers. Each performs all the physical layer interface functions for 100BASE-TX full-duplex or half-duplex Ethernet on Category 5 twisted-pair cable and 10BASE-T full or halfduplex Ethernet on Category 3, 4 or 5 cable. Each port may also be configured for 100BASE-FX full or half-duplex transmission over fiberoptic cabling when paired with an external fiber-optic line transceiver.
