BCM6315 single-chip V-thernettransceiver design based many years experience technology products. designed low-cost, long-reach Ethernet applications employing telephone-grade wiring. BCM6315 offers switch, DSLAM vendors unmatched capability provision high-speed data transmission services such Internet access extensions MDU, MTU, hospitality campus environments. BCM6315 easily configured support many popular data rates such symmetric Mbps. also offers spectral plans with asymmetric data rates Mbps upstream Mbps downstream. Either plan configured spectrally
compatible with HomePNA. chip's (Frequency Division Duplex) scheme makes ideal solution overcome performance limitations crosstalk riser wire bundle. With small footprint, BCM6315 ideal NIC, card, modem switch DSLAM designs. Automatic link initialization software available with BCM96315 V-thernetreference design package, supporting symmetric asymmetric profiles. software been ported reference design also available source code format. BCM6315 includes equalizer, FEC, interleaver, Mod, Demod, Packet Format Logic, D/A.
