Order Codes Part Number TDA7513T Package TQFP80 DESCRIPTION The TDA7513T is the first device for car-radio applications that bines full RF front-end functions with audio-processing capabilities. As far as FM and AM functions are concerned , the TDA7513T 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, FM noise blanking. The FM stereo decoder and noise blanker functions are realized entirely without external ponents. The audio processor section prises input se Figure 2. Pins Connection FMIFAMP1OUT lectors for two quasi-differential external sources, volume control, tone control (bass, mid and treble), balance and fading control to drive four output channels. 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 I2C bus allows furthermore the user to realize the full electric alignment of all the external coils, therefore removing the need for hand-made or mechanical adjustments.
