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).

Weight

For adopting ceramic discriminator and ceramic resonator, it

is not necessary to adjust the FM quad detector circuit and

FM ST DET VCO circuit.

SDIP24−P−300−1.78: 1.2g (typ.)

SSOP24−P−300−1.00 : 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.

Built−in one terminal type AM low cut circuit.

TA2053F is reverse pin type of TA2012F.

Operating supply voltage range (Ta = 25°C)

= 1.8~8.0V
