Overview
TA8132AN / AF , TA2012N / F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8132AN,TA8132AF,TA2012N,TA2012F 3V AM / FM IF + MPX (For Digital Tuning System) TA8132AN, TA8132AF and TA2012N, TA2012F are the AM / FM IF+ST DET system ICs, which are designed for DTS radios.
These are included many functions and these can be used for digital tuning system with IF counter.
Features · Built−in AM / FM IF and FM stereo PLL multiplex decoder.
· Suitable for combination with digital tuning system which is included IF counter.
○ One terminal type AM / FM IF count output (auto stop signal) for IF counter of digital tuning system.
FM: 10.
7MHz or 1.
3375MHz (1 / 8 dividing) changeable by external switch AM: 450kHz ○ Built−in mute circuit for IF count output.
It is controlled by the IF request signal from digital tuning system, Pin(8) level: High → come out Low → non output ○ Adjustable for IF count output sensitivity by external resistance of pin(2).
· For adopting ceramic discriminator and ceramic resonator, it is not necessary to adjust the FM quad detector circuit and FM ST DET VCO circuit.
