Ottawa-based Mitel Corp. released its MT312 and MT351 decoder chips, which, it reports, are designed to boost satellite and terrestrial digital TV performance.

Both allow systems to detect and tune digital TV channels delivered by satellite and terrestrial links, and include the digital functionality needed for interactive services.

The MT312 is a single-chip variable rate digital Quadrature Phase Shift Keying satellite decoder that integrates two, 6-bit ADC converters and a controller for acquisition and tracking modes for minimal interaction, maximum flexibility and fast auto-scan capability. The MT312 scans the complete Astra band in fewer than 10 seconds.

The MT 351 uses advanced COFDM technology for use in low carrier-to-noise ratios. It's designed to give broadcasters wider coverage, lower power dissipation and enhanced reception, Mitel reports. It's also designed to be easy to program, minimize software control overhead on the main system processor and provide fast autosearch capability. In the United Kingdom, the MT351 scans the complete UHF band in fewer than six seconds.
