The TDA7514 is a device for car-radio applications
that combines full RF front-end functions with ad-
vanced audio-processing capabilities.
As far as FM and AM functions are concerned, the
TDA7514 features front-end processing, including
the digital tuning PLL. IF processing with demodu-
lation and variable-bandwidth IF filtering (ISS),
stop station and quality detection functions, FM
stereo decoding by means of a fully integrated ad-
justment-free dedicated PLL and, finally, AM and
FM noise blanking (AM noise blanking comprises
one IF NB as well as an audio NB).
The FM stereo decoder and the noise blanking
functions are realised entirely without external
components. The FM front-end circuit features an
image-rejection mixer that allows the simplification
of the external preselection filter, and a very low
noise level that allows getting rid of the external
preamplifier with no loss in sensitivity. A 6 bit on-
DESCRIPTION
board ADC makes a digitised version of the Sme-
ter available to the
μ
P via I

Cbus.
The audio processor section comprises input se-
lectors for one stereo single-ended source, one
stereo quasi-differential source and a mono differ-
ential source. Volume, loudness, tone (bass and
treble), balance and fading controls are available
with completely pop-free operation to drive four
output channels. An additional input independent-
ly mixable on each of the four outputs is provided
for chime. A soft mute function and an RDS mute
function are included to handle source change as
well as RDS AF search without abrupt changes in
the audio level.
Most of the parameters in the front-end section are
I

Cbus-driven and therefore under the control of
the car-radio maker. The I

Cbus allows further-
more the user to realise the full electric alignment
of all the external coils.
