The BCM6345 combines a G.992.1/G.992.2/T1.413 ADSL
transceiver and AFE with a high-performance MIPS32
TM
CPU, a
10/100 Ethernet interface, a USB 1.1 transceiver, a PCMCIA
interface, and a generic and flexible expansion bus into a single chip.
The embedded ADSL transceiver and AFE supports full-rate G.dmt,
T1.413, and G.Lite ADSL modems 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 customer application development with
industry-standard EJTAG/Ethernet tool chains and development
environments.
A full-featured ATM SAR supports full traffic shaping,
management, and QoS for multiple VCs.
The embedded USB 1.1 transceiver and 10/100 Ethernet
MAC/PHY (with auto-MDIX) provide connectivity to a PC host.
The PCMCIA interface supports wireless networking such as
Broadcom's 802.11a/b or BluetoothTM chipsets, whereas the
flexible expansion bus allows for seamless connectivity to
Broadcom's 32-Mbps HomePNA 2.0 or other advanced
peripherals.
The BCM6345 enables a complete ADSL CPE router to be
assembled with a minimal set of additional components. The
result is the most cost-effective solution for a variety of ADSL
CPE bridging and routing applications.
