●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.
●S curve characteristics of FM detection output in TA8132AN, TA8132AF and TA2012N, TA2012F are reverse to
●each other.
● TA8132AN, TA8132AF: Reverse characteristic.
● TA2012N, TA2012F: Normal characteristic.
●Built−in one terminal type AM low cut circuit.
●TA2053F is reverse pin type of TA2012F.
●Operating supply voltage range (Ta = 25°C)
● VCC (opr.)= 1.8~8.0V
