Description
The Realtek RTL8671B / RTL8671BH are integrated SoC featuring a RISC, an ADSL2+ Discrete Multi-tone (DMT) data-pump, a hardware-based ATM Segmentation and Reassembly (SAR), two 10/100Mbps IEEE 802.3 compliant MACs with an embedded Ethernet transceiver, and a USB PHY port. Mated with the Realtek RTL8271B (ADSL2+ Analog Front End), RTL8671B RTL8671BH provide a low cost integrated solution for ADSL2+ CPE modems, routers, or gateways.
RTL8671B / RTL8671BH encompass high-performance DSP technologies, optimized mix-signal
designs, and an efficient 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 340MHz clock rate in a six-stage pipeline to support layer 2, 3, and
other upper layer applications.
Features
1. Two-chip ADSL2+ CPE solution:
RTL8671B/ RTL8671BH (ADSL2+/Network Processor SoC) + RTL8271B (ADSL2+Analog Front End).
2. Field proven DMT data-pump complies with ANSI T1.413 Issue 2, ITU-T G992.1, G.992.2 , G.992.3, G.992.4, G.992.5 supporting Annexes A, B, I, J, L, and M.Supports S=1/3 coding.
3. High performance embedded RISC with MMU, TLB and DSP instruction extension.
