The
BCM6315
is a single-chip V-thernet transceiver design
based on many years experience of QAM technology and LAN
products. 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
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-thernet 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.
