Yenra : Networking : MoCA Compatible Cable Tuners : New 1-GHz tuner chipset offers immunity from in-home networking standard interference


Microtune has introduced two new 1.1 GigaHertz (GHz) TV tuner chips that, when integrated into advanced 1-GHz set-top boxes, permit cable operators to provide their customers a no-new-wires digital in-home network. Based on Cable Labs DOCSIS and Open Cable specifications, the two new MicroTuner chips are the perfect companion tuners for personal video recorder (PVR) set-top boxes supporting the Multimedia over Coax Alliance (MoCA) specification.

Microtune's tuners, the MT2022 DOCSIS Set-top Gateway (DSG) Tuner and the MT2122 Analog/Digital Video Tuner, are the first 1.1-GHz tuners in the industry and are MoCA-compatible without additional filtering.

MoCA is a standard used by the cable, satellite, and telephony industries for moving content using the existing coaxial cabling. MoCA allows end users to transfer their personal video, music, data and pictures from one device to another within the home using existing coax.

The MicroTuner MT2122 is a fully integrated single-chip tuner specifically designed to enable high-performance analog and digital OpenCable PVR set-top boxes. The MicroTuner MT2022 is a fully integrated single-chip tuner specifically designed to enable DOCSIS Set-top Gateway (DSG) functionality.

Because MoCA transmissions share the same coaxial wiring that delivers cable content into the home, MoCA-enabled set-top boxes must be robustly designed to prevent MoCA transmissions from interfering with cable entertainment and data services.

The Multimedia over Coax Alliance develops industry specifications for delivering high-bandwidth digital content over in-home coaxial cables.
