MT2130

RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2130 SINGLE-CHIP LOW POWER TERRESTRIAL TUNER PRODUCT BRIEF The MT2130 is a single-chip low-power tuner for analog and digital worldwide television standards. MT2130 Single-Chip Tuner The MicroTuner™ MT2130 is an advanced low-power terrestrial TV tuner, optimized for portable and power sensitive devices. It has been developed to give manufacturers design flexibility and low cost while maintaining high sensitivity. The MT2130 receives frequencies in the 48 MHz to 1 GHz range and converts a selected channel to a standard intermediate frequency (IF) between 30 MHz and 57 MHz. The MT2130’s dual-conversion architecture allows for operation of both terrestrial and cable systems without any manual adjustments. This is achieved via the combination of Microtune’s ClearTune technology and an autonomous automatic gain control (AGC). The integrated LNA delivers excellent sensitivity. The innovative gain control and power detector circuits provide reliable terrestrial performance even in hostile signal environments. The MT2130 can interface with multiple TV transmission standards including ATSC, DVB-T, NTSC, PAL, SECAM and QAM. In addition, the MT2130 provides excellent in-band flatness, as well as consistent gain characteristics across the complete reception band for use in USB TV Receivers, Express Card TV Receivers, portable TVs and TV tuner modules for laptop computers.
