DESCRIPTION
The TDA7514 is a device for car-radio applications that combines full RF
front-end functions with advanced 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 demodulation
and variable-bandwidth IF filtering (ISS), stop station and quality detection
functions, FM stereo decoding by means of a fully integrated adjustment-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 board ADC makes a
digitised version of the Sme ter available to the µP via I2Cbus.
The audio processor section comprises input selectors for one stereo single-
ended source, one stereo quasi-differential source and a mono differential
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 independently 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 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.
