2 DESCRIPTION  
The TDA7514 is a device for car-radio applications  
that combines full RF front-end functions with ad-  
vanced audio-processing capabilities.  
board ADC makes a digitised version of the Sme-  
ter available to the µP via I2Cbus.  
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.  
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-  
Most of the parameters in the front-end section are  
I2Cbus-driven and therefore under the control of  
the car-radio maker. The I2Cbus allows further-  
more the user to realise the full electric alignment  
of all the external coils.
