Broadcom Corporation - BCM5248 - 10/100BASE-TX/FX TransceiverThe Broadcom BCM5248 is a 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.
