G.992.3/G.992.5/T1.413 (Issue II) deployments supporting
Annex A, B C, J, I, L, and M
High-performance MIPS32™ CPU with MMU and TLB
support
Hardware ATM SAR for enhanced ATM VC management,
traffic shaping, and QoS
Two 10/100-Mbps IEEE 802.3u Ethernet MACs and one
PHY with auto-MDIX
Configurable USB host and device interface with integrated
transceiver
Multi-format peripheral expansion bus with PCI, mini-PCI,
CardBus, and PCMCIA support
Serial and parallel FLASH support and high-speed
SDRAM interface
Extensive on-board chip power management, EJTAG,
GPIO, and UART
1.2-mm package ball pitch for reduced PCB design
complexity
Complete protocol and application software support
package

Unmatched integration greatly reduces bill of materials
cost to enable lowest possible product cost for worldwide
deployment of ADSL modems, routers, and gateways

High-resolution A/D and D/A converters minimizes system
bill of materials costs by reducing the need for external
filtering

High-performance MIPS32 CPU supports advanced
application development and future downloadable service
models with industry-standard tool chains and operating
systems

Support for wire-speed bridging and routing between
ADSL and LAN interfaces on a single-chip significantly
reduces development time, decreases time-to-market, and
increases product flexibility

Two 10/100-Mbps Ethernet MACs with MII and one 10/
100-Mbps Ethernet PHY interface with auto-MDIX
supports true Ethernet-to-Ethernet bridging and routing
as well as DMZ interface applications

Dual USB host and device interfaces enable simultaneous
Plug and Play connection of PCs and peripheral devices
including printers and hard disks

High-speed external bus with industry standard PCI, mini-
PCI, CardBus, and PCMCIA support provides glueless
interface to Broadcom and 3
rd
party voice, WiFi
®
, security,
video encoding and decoding and other peripheral chipsets

Broadcom-enhanced protocol and applications software
provides consistent, proven software architecture across all
Broadcom DSL CPE and PON ONT chipsets
