| MI C R O T U N E(R) RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT1384WFC AM/FM TUNER MODULES PRODUCT BRIEF The MT1384WFC is a high-end AM/FM tuner module with integrated dynamic selectivity which supports worldwide AM and FM bands. MT1384WFC AM/FM Tuner Module The MT1384WFC AM/FM Tuner Modules are high-end products specifically designed to meet the demanding performance, market, and pricing targets of automotive customers. The MT1384WFC AM/FM Tuners combine the low system integration effort of a standard "plug and play" module with outstanding features and absolute high-end performance. These tuner modules offer world standard functionality by supporting the various frequency allocations in the US, Europe, and Asia (including Japan). The MT1384WFC Tuner Modules are available with either horizontal-mount mechanics or vertical-mount mechanics. Special custom-designed versions are available on request. The AM section of the tuner module contains an up/down conversion system with an active prestage and an audio output. Features such as excellent sensitivity and very good large signal performance, together with the functionality of the implemented noise blanker, help ensure that the tuner module produces clear AM reception - even in critical situations. The FM section of the module contains a double down-conversion system with a selective prefilter circuit and MPX signal, as well as an RDSMPX signal output. Using appropriate external signal processing, the stereo signal and the RDS/RBDS data can be derived from these outputs. The dynamic selectivity function continuously evaluates the current receiving situation and the current modulation, and controls the optimum IF bandwidth automatically. The dynamic threshold extension automatically improves the S/N ratio at low RF input levels. Using these features, the MT1384WFC Tuner Modules produce audible signals where standard tuners produce only noise and interference.
