| BCM6348 (R) BCM6348 SINGLE-CHIP ADSL2+ CPE CHIP FEATURES * Single-chip ADSL2+ CPE device with integrated CPU, transceiver and AFE * Standards compliant for worldwide G.992.1/G.992.2/ G.992.3/G.992.5/T1.413 (Issue II) deployments supporting Annex A, B C, J, I, L, and M * High-performance MIPS32TM 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 SUMMARY OF BENEFITS * 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, miniPCI, CardBus, and PCMCIA support provides glueless interface to Broadcom and 3rd party voice, WiFi(R), 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 BCM6348-Based ADSL2+ CPE Modem 802.11b/g RJ11 ADSL Line Driver BCM6348 High-Performance Single-Chip ADSL2+ CPE Modem 10/100 Ethernet USB 1.1 FLASH SDRAM BCM6348 OVERVIEW FLASH IPSEC/AES 802.11 a/b/g Expansion Bus EJTAG V.9x DAA VoIP SLIC/ SLAC BCM6301 LD BCM6505 VDSL TDM Interface I-Cache ATM SAR System Bu s ADSL2+ AFE MIPS32 ADSL2+ Xcvr D-Cache USB MAC USB Host/Dev USB (Host/Dev) USB (Device) UTOPIA UTOPIA 2 x MII 10/100 Ethernet 10/100 Ethernet PHY 10/100 Ethernet MAC 10/100 Ethernet MAC Peripheral Bus IRQs Timers UART GPIO SDRAM Interface BCM6348 SPI SDRAM FLASH 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 BluetoothTM 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 costeffective solution for a variety of ADSL CPE bridging and routing applications.
