System Chips Enable New Telecom Services

Unveiled as the industry's most highly integrated mapper and framer chips, the Datamapper and MARS T-PHY system-on-chip (SoC) families promise efficient and cost effective transport of mission-critical services, such as wireline and wireless services, voice-over-Internet protocol (VoIP), and on-line gaming. Datamapper devices integrate more than 30 functions and are said to be the first Ethernet SONET mapper chips with integrated traffic management. Functions include a layer two processing engine and traffic manager, SONET PHY, framer, mapper, cross connect, data engine, virtual concatenation, generic framing, media access controller, SPI-3 bus, and SerDes. Also raising the density bar, the MARS-T-PHY claims title as the first framer family to combine network-hardened, 16-channel OC-3/OC-12, 4-channel OC-48, and a single OC-192 framer with 16 multi-rate, auto-detect CDR/mux/demux PHYs.
