AM radio / FM IF stereo system IC

BA1448S / BA1449F

The BA1448S and BA1449F are electronic tuning system ICs for AM, FM IF, and MPX. They have been developed for

use in radio cassette players and mini-component stereo systems.

The FM detector and MPX VCO circuits do not require adjustment, which will reduce the number of assembly line pro-

cesses. In particular, the VCO is laser locked, and requires no adjustment or external components. The characteristics

of the two chips are the same, but the packages are different (24-pin SDIP for the BA1448S and 24-pin SOP for the

BA1449F).

FApplications

Synthesized tuners in radio cassette players and mini-

component stereo systems.

FFeatures

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

and FM stereo demodulator.

6) FM MPX VCO is laser locked and requires no ad-

justment or external components.

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

3) Built-inreference voltage supply for good short-wave

band frequency stability.

7) Built-in forced monaural function for the MPX (VCO

stops, LED off).

8) Audio can be low-cut to improve AM fidelity.

9) VCO for the MPX switches off during AM operation.

10) Mute possible for IF request.

4) Good FM stability.

5) FM detector does not require adjustment (ceramic

discriminator).

FAbsolute maximum ratings (Ta = 25_C)

FRecommended operating conditions (Ta = 25_C)
