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.
