The BCM6348 combines a G.992.1/G.992.2/G.992.3/G.992.5/ T1.413
ADSL transceiver and AFE with a high-performance MIPS32 CPU, two
10/100-Mbps Ethernet interfaces, USB (host/device) transceiver,
expansion bus interface supporting PCI, mini-PCI, CardBus, and
PCMCIA into a single, high-performance chip.
The embedded ADSL transceiver and AFE implement G992.5
(ADSL2+), G.dmt, T1.413, and G.Lite ADSL, along with G.997.1,
G.994.1, I.432 TC layer, dual-latency framing, NTR, and embedded
operations channels for remote management of the CPE.
The embedded MIPS32 CPU, with Broadcom-supplied software,
controls the ADSL modem, performs high-performance bridging and
routing between the ADSL WAN interface and various LAN interfaces,
and allows for custom application development with industry-standard
EJTAG/Ethernet tool chains and development environments.
A full-featured ATM SAR supports complete traffic shaping,
management, and QoS for multiple VCs. The embedded USB (host/
device) transceiver, two 10/100-Mbps Ethernet MACs, and one PHY
(with auto-MDIX) provide connectivity to PC hosts as well as optional
10/100/1000-Mbps Ethernet switches.
The expansion bus interface supports seamless connectivity to wired and
wireless networking peripheral chips such as Broadcom’s 802.11a/b/g or
Bluetooth™ chipsets via PCI, mini-PCI, CardBus, and PCMCIA, as well
as Broadcom’s V.92, security processors, and other advanced
peripherals.
The BCM6348 enables a complete ADSL CPE router to be assembled
with a minimal set of additional components resulting in a most cost-
effective solution for a variety of ADSL CPE bridging and routing
applications.
