TUA 4306
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.

VF - Dynamic :The dynamic range of VF voltage is determined by
the test points M1 through M4 as follows:
M1: test point (at ViIF= 50 dBµV) supplies VF (M1)
M2: test point (at ViIF= 90 dBµV) supplies VF (M2)
M3: test point (at ViIF= 20 dBµV) supplies VF (M3)
M4: test point (at ViIF=120 dBµV) supplies VF (M4)
Hence follows :
VF (M4) - VF (M2)
MVFmax:= 90 dBµV+––––––––––––––––– × 40 dB
VF (M2) - VF (M1)
VF (M1) - VF (M3)
MVFmin:= 50 dBµV - ––––––––––––––––– × 40 dB
VF (M2) - VF (M1)
VF - Dynamic = MVFmax - MVFmin

VF - Linearity:
is determined at 25 °C
Slope
VF (M2) - VF (M1)
: m= ––––––––––––––––––
40 dB
The tolerance range of the VF - linearity is determined by
two parallel lines:
VFmax = VF (M1) + m (M + 60 dB+ 1dB)
VFmin = VF (M1) + m (M + 60 dB - 1dB)
The VF values within the VF dynamic range
(MVFmin≤M≤MVFmax)
must be inside the predetermined tolerance range:
VFmin ≤ VF ( M ) ≤ VFmax

The tolerance range of the VF temperature drift is determined
by two parallel lines:
VFmax = VF (M1) + m (M + 60 dB+ 3dB)
VFmin = VF (M1) + m (M + 60 dB - 3dB)
The VF values for temperatures between -40 to +85 °C within
the VF dynamic range (MVFmin≤VF≤MVFmax) must be
inside the predetermined tolerance field:
VFmin≤ VF ( M ) ≤ VFmax
