Product Summary
The BCM5228UA4IPFG is a 10/100 BASE-TX/FX OCTA L-Φ. transceiver. It is a single-chip device containing eight independent Fast Ethernet transceivers. Each transceiver performs all of the physical layer interface functions for BCM5228UA4IPFG full-duplex or half-duplex Ethernet on Category 5 unshielded twisted pair (UTP) cable and 10BASE-T full-duplex or half-duplex Ethernet on Category 3, 4 or 5 UTP cable. Each port may also be configured for BCM5228UA4IPFG full-duplex or half-duplex transmission over fiber optic cabling when paired with an external fiber optic line driver and receiver.
