RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT1501 EDC DAB TUNER MODULE PRODUCT BRIEF The MT1501 tuner module is designed for terrestrial digital audio broadcasting (DAB) in high-end automobile radios and entertainment system. The MT1501 EDC DAB Tuner Module is designed for VHF Band III and L-Band reception according to the Eureka 147 DAB standard. It has been optimized to meet the specific requirements for mobile applications and to provide superior performance under extreme environmental conditions (-40 to +85 °C). The MT1501 module features a down-conversion to a fixed IF which can be demodulated by an appropriate external channel decoder. An internal closed-loop AGC automatically controls the IF output level. The threshold level can be set by the serial bus. The MT1501 module also features digitally aligned tracking filters for both bands as well as an IF SAW filter in order to minimize interferences and distortion caused by undesired signals or adjacent channels. The antenna matching is also digitally aligned. An integrated EEPROM is provided to store these alignment data. By using the WAGC input pin the external demodulator can freeze the integrated AGC circuit to keep the IF output level unchanged during the null symbol of the DAB signal. This prevents the A/D converter from clipping as the transmission resumes. A 12V DC phantom power supply can be routed from the pin connector to the antenna input of an active antenna system. Moreover a level indicator circuit provides a DC-voltage dependent on the RF-input level. The MT1501 module fully complies with RoHS requirements. Customized mechanics and connectors are available on request.
