Octal-Port Copper/Fiber Fast Ethernet Transceiver
Single-chip device containing eight independent Fast Ethernet transceivers. Each performs all the physical layer functions for 100BASE-TX full- or half-duplex Ethernet on Category 5 UTP cable and 10BASE-T full- or half-duplex Ethernet on Category 3, 4 or 5 UTP cable.
The BCM5248 chip performs encoding and decoding, clock and data recovery, digital adaptive equalization, line transmission, carrier sense and link integrity monitoring, autonegotiation and SMII/SSSMII management functions. The BCM5248 is compliant with the IEEE 802.3 standard. The BCM5248 offers alternative connection to fiber-optic modules for 100BASE-FX operation. The Enhanced FX mode allows 100BASE-FX operation without the use of Signal Detect pins. The standard FX mode allows 100BASE-FX operation with modules that require the PHY to use Signal Detect inputs to disable receive data in the absence of a received optical signal.
