ADSL2+ ROUTER SOC SOLUTION

General Description:
The Realtek RTL8671/RTL8671P are integrated SoCs featuring a RISC, an ADSL2+ Discrete MultiTone (DMT) datapump, a hardware ATM Segmentation and Reassembly (SAR), a 10/100Mbps IEEE 802.3 compatible MAC with Ethernet transceiver, and a PCI host/device bridge interface. Together with the Realtek RTL8271 (ADSL2+ Analog Front End), the RTL8671/RTL8671P provide a low-cost integrated solution for ADSL2+ CPE modem, router, or gateway.

The RTL8671/RTL8671P incorporate high-performance DSP technologies, optimized mixed-signal designs, and an efficient system architecture to provide a seamless WAN to LAN router controller. The embedded RISC network processor supports the MIPS I instruction set along with DSP extensions, and achieves a 200MHz clock rate in a six-stage pipeline to support layer 2, 3, and other upper layer applications.
