IF amplifier/demodulator for FM radio receivers
TDA1597
Consequently, there is no need for the demodulator tuned
circuit to be adjusted for minimum distortion. Adjustment
criterion is a symmetrical stop pulse. The control voltage
for the mute attenuator (pin 16) is derived from the values
of the level detector and the detuning detector output
signals. The mute attenuator has a fast attack and a slow
decay, determined by the capacitor connected to pin 16.
The AF signal is fed via the mute attenuator to the output
(pin 4). A weighted control voltage (pin 6) is obtained from
the mute attenuator control voltage via a buffer amplifier
that introduces an additional voltage shift and gain.
FUNCTIONAL DESCRIPTION
The limiter amplifier has five stages of IF amplification
using balanced differential limiter amplifiers with emitter
follower coupling.
Decoupling of the stages from the supply voltage line and
an internal high-ohmic DC feedback loop gives a very
stable IF performance. The amplifier gain is virtually
independent of changes in temperature.
The FM demodulator is fully balanced and contains two
cross-coupled differential amplifiers.
The level detector generates a voltage output signal
proportional to the amplitude of the input signal.
The unweighted level detector output signal is available in
the FM-MUTE-ON condition (mode switch).
The quadrature detection of the FM signal is performed by
direct feeding of one differential amplifier from the limiter
amplifier output and the other via an external 90 degrees
phase shifting network. The demodulator has a good
stability and a small zero cross-over shift. The bandwidth
of the demodulator output is restricted by an internal
low-pass filter to approximately 1 MHz. Non-linearities,
which are introduced by demodulation, are compensated
for by the THD compensation circuit. For this reason, the
demodulator resonance circuit (between pins 10 and 11)
must have a loaded Q-factor of 19.
The open-collector tuning stop output voltages STOP-0
and STOP-1 (pins 15 and 14) are derived from the
detuning and the input signal level. Pins 14 and 15 may be
tied together if only one tuning-stop output is required.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

SOLDERING
BY SOLDER PASTE REFLOW
Reflow soldering requires the solder paste (a suspension
of fine solder particles, flux and binding agent) to be
applied to the substrate by screen printing, stencilling or
pressure-syringe dispensing before device placement.
Plastic dual in-line packages
BY DIP OR WAVE
The maximum permissible temperature of the solder is
260 °C; this temperature must not be in contact with the
joint for more than 5 s. The total contact time of successive
solder waves must not exceed 5 s.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt, infrared, and
vapour-phase reflow. Dwell times vary between 50 and
300 s according to method. Typical reflow temperatures
range from 215 to 250 °C.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified storage maximum. If the printed-circuit board has
been pre-heated, forced cooling may be necessary
immediately after soldering to keep the temperature within
the permissible limit.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 min at 45 °C.
REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING
IRON OR PULSE-HEATED SOLDER TOOL)
REPAIRING SOLDERED JOINTS
Fix the component by first soldering two, diagonally
opposite, end pins. Apply the heating tool to the flat part of
the pin only. Contact time must be limited to 10 s at up to
300 °C. When using proper tools, all other pins can be
soldered in one operation within 2 to 5 s at between 270
and 320 °C. (Pulse-heated soldering is not recommended
for SO packages.)
Apply a low voltage soldering iron below the seating plane
(or not more than 2 mm above it). If its temperature is
below 300 °C, it must not be in contact for more than 10 s;
if between 300 and 400 °C, for not more than 5 s.
Plastic small outline packages
BY WAVE
For pulse-heated solder tool (resistance) soldering of VSO
packages, solder is applied to the substrate by dipping or
by an extra thick tin/lead plating before package
placement.
During placement and before soldering, the component
must be fixed with a droplet of adhesive. After curing the
adhesive, the component can be soldered. The adhesive
can be applied by screen printing, pin transfer or syringe
dispensing.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder bath is
10 s, if allowed to cool to less than 150 °C within 6 s.
Typical dwell time is 4 s at 250 °C.
A modified wave soldering technique is recommended
using two solder waves (dual-wave), in which a turbulent
wave with high upward pressure is followed by a smooth
laminar wave. Using a mildly-activated flux eliminates the
need for removal of corrosive residues in most
applications.
