3 OVERVIEW The NT1022 is multiband multistandard direct-conversion TV tuner designed for Mobile Digital TV applications. The TV tuner supports DVB-H, DVB-T, IP-DAB, T-DMB, FM standards and covers FM (75 MHz to 108 MHz), VHF (170 MHz to 240 MHz), UHF (470 MHz to 860 MHz) bands and L-band (both 1450 MHz to 1490 MHz and 1660 MHz to 1685 MHz). So it is suitable for digital TV reception on portable devices almost anywhere in the world. Based on direct-conversion architecture with zero-IF NT1022 is optimal solution for television signal receiving. The TV tuner is a highly integrated circuit therefore a few external components are required. A programmable serial interface allows status monitoring and controlling all the internal operations and test modes. The IC is fabricated on TSMC 0.18 um SiGe BiCMOS technology.
