MT1503EDC

RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT1503EDC DAB/DMB TUNER PRODUCT BRIEF The MT1503EDC is a high-end tuner module with integrated channel decoding and baseband processing capabilities for terrestrial digital audio broadcasting (DAB). It has been designed to meet the specific requirements of automotive applications. MT1503EDC DAB/DMB Tuner The MT1503EDC is a tuner module for reception in VHF Band III and L-Band compliant to the DAB EUREKA 147 standard. It performs a down-conversion to an intermediate frequency followed by further signal processing based on an integrated baseband processor. A serial bus interface serves as a digital audio output. In order to minimize interferences and distortion caused by undesired signals of adjacent channels the tuner section of the MT1503 features digitally aligned tracking filters and an IF SAW filter. The integrated flash memory stores the necessary alignment data and the software for the baseband processor. The MT1503EDC supports a variety of possible applications by decoding FIC/FIDC and PAD data which is used to broadcast dynamic labels, traffic information, slideshows, websites as well as information needed for station following and announcement switching. A standardized Raw Data Interface (RDI) and a Serial Peripheral Interface (SPI) grant access to the full DAB audio and data stream to enable an easy connection of external decoders for additional data services and mobile TV applications. All tuner and DSP functions are controlled by a Universal Synchronous/ Asynchronous Receiver/Transmitter (USART) interface. Active antenna systems as commonly used for automotive applications can be fed with 12V phantom power which is routed from a pin connector to the antenna input of the module. The MT1503EDC is lead free and fully complies with RoHS requirements. It has been optimized to meet the specific requirements for automotive applications and provides reliable performance even under harsh environmental conditions like temperatures from -40°C to +85°C.
