| RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT145X SERIES AM/FM TUNER MODULES PRODUCT BRIEF The MT145X series tuner modules, supporting world standards, are designed for high-end automotive radios with digital IF. MT145X Series Tuner Module The MT145X Series AM/FM Tuner Modules are designed specifically for high-end automotive radio and mobile entertainment systems. They are optimized to meet the performance, market and pricing demands of automotive OEM customers. Supporting the various AM/FM frequency allocations in the US, Europe and Asia (including Japan) the tuner modules offer worldwide functionality. The 10.7 MHz IF output interfaces with a dedicated DSP (e.g. STMicroelectronics TDA7580 or TDA7581) to form a DSP-based digital AM/FM radio. New broadcasting standards like HD-RadioTM or DRM are supported as an option. In addition, a FM-only version of the tuner is available in order to add highly sophisticated features like FM phase diversity to the system. MT145X modules also incorporate a high-performance fast PLL for inaudible checking of alternative frequencies within RDS networks. For FM mode, a keyed AGC function is implemented to prevent receiver desensitization due to erroneous AGC response while in AM mode, a narrow band filter improves selectivity. Superb sensitivity is also provided for MW/LW/SW reception. Moreover the modules feature an automatic alignment for the tracking filter and the image rejection filters. All alignment data is stored on an onboard EEPROM which can be accessed by a serial bus interface like all the other tuner functions. The MT145X series modules were qualified under typical automotive operating conditions and fully comply with RoHS requirements. Modules are available in a shielded horizontal (optional vertical) housing.
