MSP7150/MSP7140 gateway SoCs from PMC-Sierra

PMC-Sierra Inc. has introduced its two fibre access gateway SoCs that deliver gigabit-per-second line-rate IPV4/V6 routing, network address translation (NAT), QoS, encryption and a multi-channel VoIP terminal adaptor. The MSP7150 EPON/GPON gateway SoC for fibre-to-the-home (FTTH) and the MSP7140 VDSL2 gateway SoC for fibre-to-the-node (FTTN) consume less than 1.5W of power.

PMC-Sierra's fibre access gateway solutions provide OEMs and ODMs with a common platform architecture to support multiple high-speed access technologies in various geographic markets. Moreover, service providers can rely on equipment based on PMC-Sierra's multi-service platform to deliver carrier-grade IP services into the digital home.

Powered by a 600MHz MIPS processor core with hardware multi-threading, the MSP7140/50 solutions deliver high performance to support high bandwidth LAN interface technologies and fully programmable packet processing acceleration to accommodate future service models and home network configurations.

The solutions also enable headroom to support gateway-hosted applications, such as integrated storage/media server, fixed mobile convergence clients, and remote access servers. The devices contain a Linux-based OS that allows for the leveraging of industry-standard middleware.

The MSP7140/50 integrate three gigabit ports, two USB 2.0 full-speed PHYs (physical interfaces), a 66 MHz PCI bus, DDR2 memory controller, multi-channel VoIP terminal adapter, IPSec accelerator and hardware protection against small packet flooding to protect critical services from packet loss during periods of high network activity.

MSP7150 supports both IEEE 802.3ah-compliant EPON and ITU-T G.984-compliant GPON fibre access gateway solutions. With an integrated VDSL2 modem, MSP7140 is a suitable solution for multi-service VDSL2-based gateway. MSP7140 is claimed to be the first to demonstrate VDSL2 interoperability with all installed central office VDSL1 and VDSL2 chipsets and is backwards compatible to ADSL2+.

PMC-Sierra offers the following designs and development platforms, including BOM-cost optimised schematics, gerbers and documentation: PM2330-KIT for EPON, PM2331-KIT for GPON, PM2329-KIT for VDSL2 and PM2332-KIT for GbE fibre access gateways.

An MSP7100 SDK, with Linux OS, networking stack, Linux APIs, VoIP Processing Module and a MIPS software development toolchain package, is available to support the development and leverage the power of the Linux ecosystem.
