Circuit Description
General Description The TUA 4306 is a one chip car radio system consisting of AM/FM receiver, AM-Up/Down conversion, AGC amplifier / demodulator, FM-IF limiter amplifier / demodulator and stereodecoder / noiseblanker.
4.1 AM/FM-Receiver
The AM/FM-receiver part includes a 2-pin varactor tuned oscillator. In the FM mode the direct oscillator frequency is fed into the double balanced FM mixer, in the AM mode the divided by 4, 6, 8 or 10 oscillator frequency is fed into the AM mixer. The two separate symmetrical input stages of the IC, one optimized for FM-, the other for AM- mode allow symmetrical and unsymmetrical prestage configuration. The AM and FM input frequencies are converted to a fix 1st IF in the 10.7 MHz range. The FM-IF is post amplified in a separate IF amplifier with DC adjustable gain, the AM-IF is fed directly to the 2nd mixer. The TUA 4306 has been designed to work with a PLL in the 100MHz range in both modes or in the AM- mode with the divided frequency. Depending on the input signal strength, the integrated AGC stage for prestage control drives PIN-Diodes as well as MOSFETs.
4.2 FM-MODE
FM-IF Demodulator The FM-IF amplifier includes a 7 stage capacitive coupled limiter amplifier with coincidence demodulator and AF output. The AF output signal can be continuously attenuated to decrease the noise. There is a field strength output (with min. 76 dB dynamic range, typ. 1 dB nonlinearity and typ. 3 dB temperature drift) and a fixed muting (with full muting typ 80 dB). A multipath detector with analog output is available. Its input signal is fed from the high pass filter of the stereo-decoder/noiseblanker and a second 80 kHz 1-pole high pass filter.
4.3 Stereodecoder
Power supply, reference current: A temperature-stable, low noise reference voltage generator is used for better ripple rejection and to generate a reference current. This current is used as a time base for the deemphasis, the gate time of the pulse former, and the pilot cancellation, avoiding temperature and tolerance effects . MPX input, MPX filter: A 4-pole low-pass filter determines the bandwidth of the MPX signal. Voltage Controlled Oscillator, Phase Detector: The 456 kHz oscillator and the frequency dividers are used as walsh function generators (suppression of 3rd order harmonics) for: 38 kHz for the stereo decoder 19 kHz inphase for phase detector and pilot cancellation 19 kHz quadrature for the phase detector. The phase detector locks the on chip 19 kHz signal to the pilot tone in the MPX signal at 90 deg phase.
Pilot Detector, Pilot Indicator, Pilot Cancellation: The voltage at the pilot detector output is proportional to the pilot tone input level. If that level is high enough, the pilot indicator output is activated and the pilot cancellation turned on: a 19 kHz signal proportional to the voltage at the pilot detector output is added to the MPX signal with inverse polarity, cancelling the 19 kHz pilot tone. Interference Detector , Noise Detector, Pulse Former: The signal from the interference input (MPX or field strength signal) passes a 4-pole high-pass filter to the noise blanking circuitry. The average noise level is stored in an external capacitor. The interference detector compares the actual noise level with that stored on the capacitor and triggers the pulse former if there is a sig-

nificant difference. The pulse former generates a gate pulse for the HCC block. During that pulse time the outputs of the deemphasis circuit are switched to hold mode.
4.4 AM - MODE
In the AM mode the 1st IF is converted by the 2nd mixer into the 2nd IF in the 450 kHz range. Therefore a 2nd LO force input is part of the IC. The 2nd IF signal passes an automatic gain controlled IF amplifier and is then demodulated to the AF in a quasisynchronous demodulator. Switching to seek mode, the AGC time constant is reduced by a factor of 5, the AM IF counter output is switched on and the AF is muted. The AGC voltage is used as AM field strength and is fed to the combined field strength output.
