Overview: .. RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND MUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2063 SINGLE-CHIP UNIVERSAL TUNER
PRELIMINARY PRODUCT BRIEF The MT2063 is a low-power 3.3V singlechip universal tuner for analog and digital worldwide terrestrial and cable standards MT2063 Single-Chip Universal Tuner The MicroTuner™ MT2063 is an advanced, low-power single-chip tuner, optimized for terrestrial and cable television reception. The MT2063 is capable of receiving frequencies in the 48 MHz to 1002 MHz range. It can convert a selected channel to a standard intermediate frequency (IF) between 30 MHz and 60 MHz. The MT2063 dual-conversion architecture yields the desirable characteristics of traditional television tuners without the need for external tracking filters. This is achieved by an integrated preselection filter at the RF input, low in-band emissions and outstanding image rejection The MT2063 has a high level of integration to keep the total Bill of Materials (BOM) low. It supports multiple digital terrestrial television standards including ATSC, DVB-T, DMB-T and ISDB-T. In addition, MT2063 supports 256QAM reception as it is used in world wide digital cable networks and analog NTSC, PAL and SECAM signals. It provides excellent in-band flatness as well as consistent gain characteristics across the plete reception band. The integrated LNA delivers excellent sensitivity. An innovative architecture enables an AGC control range of more than 90 dB. The programmable buffered reference frequency output enables crystal sharing with the demodulator.
