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
· Builtin 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
Builtin 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.
Weight
SDIP24P3001.78: 1.2g (typ.)
SSOP24P3001.00 : 0.31g (typ.)
· 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.
· Builtin 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
