BCM6435-Based xDSL Integrated Access Device HomePNA RJ11 ADSL Line Driver 802.11 BCM6345 High-Performance Single-Chip ADSL CPE Modem Flash Memory SDRAM 10/100 Ethernet USB 1.1 B C M 6 3 4 5 Flash Memory Clock Generation Module O V E R V I E W HPNA DMA 10/100 Ethernet MAC Internal System Bus Full Rate ADSL Xcvr ADSL AFE JTAG Expansion Bus /PCMCIA NTR Line Driver 802.11 ATM SAR I-Cache 10/100 Ethernet PHY 802.3 MDI 802.3 MII USB 1.1 MAC USB 1.1 PHY Peripheral Bus MIPS32 USB 1.1 Timers D-Cache SDRAM interface IRQs UART GPIO BCM6345 SDRAM The BCM6345 combines a G.992.1/G.992.2/T1.413 ADSL transceiver and AFE with a high-performance MIPS32TM 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. 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.
