The BCM6345 combines a G.992.1/G.992.2/G.992.3/T1.413-compliant
ADSL2 transceiver and AFE with a high-performance MIPS32™ CPU,
10/100 Ethernet and USB 1.1 interfaces, PCMCIA and programmable
16-bit external bus interfaces into a single chip.
The embedded ADSL2 transceiver and AFE support the development of
full-rate G.dmt, T1.413, and G.Lite ADSL with support for 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 ADSL2 WAN interface and LAN interfaces, and
allows for customer application development with industry-standard
EJTAG/Ethernet tool chains and development environments.
A full-featured ATM SAR supports hardware traffic shaping,
management, and QoS for multiple VCs.
The embedded USB 1.1 transceiver and 10/100 Ethernet MAC and PHY
with auto-MDIX provide connectivity to a PC host. The PCMCIA
interface supports seamless connectivity to wireless networking
solutions such as Broadcom's 802.11a/b/g or Bluetooth™ chipsets.
The BCM6345 enables a complete ADSL2 CPE router to be assembled
with a minimal set of additional components. The result is the most cost-
effective solution for a variety of ADSL2 CPE bridging and routing
applications.
