FUNCTIONAL DESCRIPTION

The TDA8012AM is a low power PLL FM demodulator
designed for use in satellite TV reception systems.

The demodulator is based on a PLL structure including a
fully balanced two-pin VCO. A high gain IF amplifier
ensures a high input sensitivity. The video output voltage
is supplied through a highly-linear video buffer with a low
output impedance. The centre frequency of the VCO and
the loop characteristics can be set by external components
(see Fig.4).

1997 May 26 4

The circuit provides an AGC signal which is used to drive
a gain-controlled IF amplifier (TDA8011T or TDA8010AM)
for a stable PLL demodulation characteristic.

An analog AFC voltage is available. This signal fits in with
the input of the A/D converter port of the PLL frequency
synthesizer (TSA5055). The AFC function may be keyed
to address D2MAC systems.

The TDA8012AM includes a Carrier Detector (CD) used
for channel detection during search procedures.

measured in the application of Fig.4 with the following component values for the tank circuit:
Coil: 2.5 turns; diameter 2 mm; adjustable.
Capacitor: miniature ceramic plate capacitor NP0, 3.3 pF.

3. The circuit is designed for an input level of 57 dBµV. The maximum allowable input level for the PLL design is
61 dBµV. However, for levels different from 57 dBµV, the optimum loop filter values will be different from those given
for the 57 dBµV input level in the reference measuring set-up.

4. The input impedance is reduced to a resistor with a parallel reactance. The values are given at 480 MHz. In order to
reduce the radiation from the oscillator to the RF input, it is recommended to use a symmetrical drive.

5. The PLL loop gain shift and drift are given without loop filter shift and drift (non-temperature compensated external
components).

6. The capture range or lock-in range is defined as the range where the PLL gets in lock. This value depends strongly
on the loop filter characteristics.

7. Measurements with test signals in accordance with CCIR recommendation 473-3;
FM modulated signal with DBS parameters:

a) 625 lines PAL TV system
b) 16 MHz/V modulator sensitivity
c) 1 V (p-p) video signal
d) No SAW filter is used.

8. No SAW filter is used at the input:
a) 16 MHz/V modulator sensitivity
b) 4.43 MHz sine wave colour signal (660 mV (p-p))
c) 3.25 MHz sine wave luminance signal (700 mV (p-p))
d) CCIR pre-emphasis
e) Intermodulation distance is defined as the distance between the luminance signal and the intermodulation

products.The video output spectrum is measured on pin 11 (point A of Fig.4) with a high resistance probe.
The de-emphasis figure is obtained from the measured data by calculation.

9. No SAW filter is used at the input:
a) 16 MHz/V modulator sensitivity
b) Two sound carriers at 7.02 MHz and 7.20 MHz; 4 MHz deviation
c) Intermodulation measurement without pre-emphasis
d) Intermodulation distance is defined as the distance between one of the sound carriers and the intermodulation

products

e) The video output spectrum is measured on pin 11 (point A of Fig.4) with a high resistance probe and a spectrum

analyser.

10. Measurements are made under the following conditions
a) FM modulator video signal
b) Amplitude level: 57 dBµV
c) Frequency: 479.5 MHz
d) Frequency deviation: 16 MHz
e) CCIR pre-emphasis + unified weighting filter
f) C/N > 50 dB

S/N is measured after de-emphasis with a baseband spectrum from 200 kHz to 5 MHz.

11. The AM sensitivity is defined as the ratio of the baseband output signals obtained from either an AM or FM modulated
RF input signal.

13. For applications in which a fixed AGC threshold is used, it is recommended to use the internal resistor voltage divider
for lower AGC threshold spread. In this case, the threshold is set to 57 dBµV.

14. In the application circuit (see Fig.4) the voltage at the AGC output decreases when the IF input level increases above
the adjusted AGC threshold.

15. The outputs from the AFC and carrier detector are combined at pin 19 (see Fig.3). During search tuning, when the
input frequency is outside the capture range, the combined output (carrier detector function) is at a LOW level
(any voltage below 0.6VCC). When the PLL becomes locked, the voltage at pin 19 rises to a HIGH level
(V19= 0.8VCCto VCC). When the input channel is close to the centre frequency, V19 falls to the LOW level. As shown
in Fig.3, the voltage at pin 19 is now a function of the centre frequency (AFC function). This information may be read
by a microcontroller via the ADC of the satellite frequency synthesizer (TSA5055) and the I2C-bus.

16. This current discharges the external capacitors between two energy dispersal peak values and avoid the use of
external resistors in parallel with capacitors.

17. The drift of the automatic frequency control voltage is measured in accordance with the following method:
a) At room temperature (T

pin 20 must be adjusted to obtain a 1.5 V output at the AFC output (pin 19).

b) At T

=80°C, due to its temperature drift, the AFC output voltage differs from 1.5 V. The input frequency must

amb

be adjusted to obtain 1.5 V at the AFC output. Then the VCO frequency f
(without input signal). The drift of the automatic frequency control voltage will then be equal to the difference
between the input frequency and f

=25°C) the TDA8012AM is driven by a 480MHz unmodulated signal. The voltage at

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

Reflow soldering

Reflow soldering techniques are suitable for all SSOP
packages.

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

Wave soldering

Wave soldering is not recommended for SSOP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.

(order code 9398 652 90011).

TDA8012AM

If wave soldering cannot be avoided, the following
conditions must be observed:

• A double-wave (a turbulent wave with high upward

pressure followed by a smooth laminar wave)
soldering technique should be used.

• The longitudinal axis of the package footprint must

be parallel to the solder flow and must incorporate
solder thieves at the downstream end.

Even with these conditions, only consider wave
soldering SSOP packages that have a body width of

4.4 mm, that is SSOP16 (SOT369-1) or
SSOP20 (SOT266-1).

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Repairing soldered joints

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
