| M I C R O T U N E(R) RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2131 SINGLE-CHIP TERRESTRIAL TUNER PRODUCT BRIEF The MT2131 is a high-performance single-chip tuner for ATSC and Digital Cable-Ready ATSC television receivers and set-top boxes. MT2131 Single-Chip Tuner The MicroTunerTM MT2131 is an advanced single-chip terrestrial tuner, optimized for integrated digital televisions and ATSC set-top boxes. The MT2131 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 MT2131's dual-conversion architecture yields consistent ATSC A/74 and FCC Digital Cable-Ready (DCR) compliant performance 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 superb terrestrial performance. The MT2131 has an on-chip amplifier for Forward Data Channel (FDC) applications to reduce the total Bill of Materials (BOM) cost for a DCR television receiver. It supports multiple standards including ATSC, QAM, and NTSC. In addition, the MT2131 provides excellent in-band flatness, as well as consistent gain characteristics across the complete reception band for use in digital/analog televisions, terrestrial set-top boxes and high-performance PC-TV applications.
