| s Product Brief TUA 4307 The ONE Chip Car Radio IC The TUA 4307 is an one chip car radio front end IC consisting of an AM/FM receiver, an AM up down converter, an AGC amplifier, a FM IF limiter amplifier, AM and FM demodulators, and a stereodecoder with noise blanker. The highlight of this IC is the AM/FM station detector. Potential Application s Car radios Features AM/FM-Receiver s High flexibility with external preamplifier s Only one 2-pin-LO at 100 MHz for AM and FM s Strictly symmetrical RF parts FM-Receiver s High input/output 3rd order s FM IF counter output with request function pin s Adjustment free stereodecoder VCO with 912 kHz ceramic resonator s AM station detector with adjustable fieldstrength treshold (output combined with FM) s Output for AM stereo decoder (CQAM) Features TUA 4307 Price Projection s Standard price list s For Key and Focus accounts or high volumes you may contact your regional Siemens sales partner s Application Board TUA 4307 Development and Support Tools Benefits Alignment free One chip for all radios Cost savings, high reliability New markets (e.g. Saudi Arabia) interceptpoint FM-IF Demodulator s Multipath detector with AM UP/DOWN conversion concept Flexible for high-performance / low-cost applications Reduced number of adjustments Reduced peripheral count MW/SW receiver Packing Type TUA 4307 Documentation Specification Articles/Press releases analog output Stereodecoder s Analog mono/stereo blend control s Adjacent channel noise suppression AM Mode s Fast AM search tuning stop Add on to TUA 4306 s FM station detector with S curve Ordering Code Q66000-S-T Package P-MQFP-80-1 Date of Issue/Version 9/98 tbd. criterion and adjustable fieldstrength treshold (output combined with AM) http://www.siemens.de/semiconductor/consumer_electronic Block Diagram SNC HCC H/S VRef AM/FM to C Open C AFout Count Div Count 1.
