AM radio / FM IF stereo system IC

BA1450S

The BA1450S is a tuner system IC for electronic tuning for AM radios, FM IF, and MPX. It has been developed for Hi-Fi

component applications.

The MPX VCO circuit requires no adjustment, which will enable a reduction in the number of production line processes.

In particular, the laser lock technique used in the VCO means that no external adjustment is required.

FApplications

Synthesized tuner for Hi-Fi components.

FFeatures

1) Built-in AM monaural radio, FM IF amplifier/detector,

and FM stereo demodulator.

6) Built-in forced monaural operation function for MPX

(VCO stops, and LED goes off).

2) DTS (both SD and IF count) compatible.

3) Built-in reference voltage power supply provides

good shortwave band frequency stability.

4) Good FM stability.

7) Low cutoff of audio is possible to improve AM fidelity.

8) MPX VCO stops in AM mode.

9) Audiomuting is possible when an IF request is made.

5) The FM MPX VCO uses laser locking making adjust-

ment and external components unnecessary.

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
