It is designed for low-cost, long-reach Ethernet applications employing telephone-grade wiring. The BCM6315 offers switch, DSLAM and CPE vendors an unmatched capability for the provision of high-speed data transmission services such as Internet access and LAN extensions in MDU, MTU, hospitality and campus environments. The BCM6315 is easily configured to support many popular data rates such as symmetric 10 and 13 Mbps. It also offers spectral plans with asymmetric data rates up to 3 Mbps upstream and 52 Mbps downstream. Either plan can be configured to be spectrally PLL / Clock Generation Programmable Rate I/Q Mod A/D Acquisition/Tracking Loops compatible with HomePNA. The chip's FDD (Frequency Division Duplex) scheme makes it an ideal solution to overcome performance limitations due to crosstalk in the MDU riser wire bundle. With its small footprint, the BCM6315 is ideal for use in NIC, PC card, CPE modem switch and DSLAM designs. Automatic link initialization software is available with the BCM96315 V-thernetTM reference design package, supporting symmetric and asymmetric profiles. The software has been ported to the reference design and is also available in source code format. The BCM6315 includes an equalizer, FEC, interleaver, Mod, Demod, Packet Format Logic, A/D and D/A.
