TA2154AFN General Description

TA2154AFN is developed for 1.5 V headphone stereos. It incorporates all the functions of an FM/TV front end, AM/FM IF, and FM multiplex.

The IC can be used for IF count digital tuning systems. Sincethe IC divides the buffer output frequency by 16 while
suppressing the FM/TV local oscillation level, the IC can suppress unnecessary emission, facilitating conformance to the new FCC specifications (part 15).
