VIF-PLL demodulator and FM-PLL detector TDA9800

FUNCTIONAL DESCRIPTION
Vision IF input

The vision IF amplifier consists of three AC-coupled
differential amplifier stages; each stage comprises a
controlled feedback network by means of emitter
degeneration.

IF and tuner AGC

The automatic control voltage to maintain the video output
signal at a constant level is generated according to the
transmission standard. Since the TDA9800 is suitable for
negative modulation only the peak-sync level is detected.
The AGC detector charges and discharges the capacitor
on pin 19 to set the IF gain and the tuner gain. The AGC
capacitor voltage is transferred to an internal IF control
signal, and is fed to the tuner AGC to generate the tuner
AGC output current on pin 12 (open-collector output). The
tuner AGC voltage take over point is adjusted on pin 3.
This allows the tuner and the IF SAW filter to be matched
to achieve the optimum IF input level.

Frequency detector, phase detector and video demodulator

The IF amplifier output signal is fed to a frequency detector
and to a phase detector. During acquisition the frequency
detector produces a DC current which is proportional to the
frequency difference between the input and the VCO
signal. After frequency lock-in the phase detector
produces a DC current proportional to the phase
difference between the VCO and the input signal. Via the
loop filter the DC current of either frequency detector or
phase detector is converted into a DC voltage, which
controls the VCO frequency.
The video demodulator is a linear multiplier, designed for
low distortion and wide bandwidth. The vision IF input
signal is multiplied by the in-phase component of the VCO
output. The demodulated output signal is fed via an
integrated low-pass filter (f
amplifier for suppression of the carrier harmonics.

= 12 MHz) to the video

g

with 90 degree phase difference independent of
frequency.

Video amplifier, buffer and noise clipping

The video amplifier is a wide bandwidth operational
amplifier with internal feedback. A nominal positive
modulated video signal of 1 V (p-p) is present on the
composite video output (pin 13). The input impedance of
the 7 dB wideband buffer amplifier (with internal feedback)
is suitable for ceramic sound trap filters. The CVBS output
(pin 7) provides a positive video signal of 2 V (p-p). Noise
clipping is provided internally.

Sound demodulation

The FM sound intercarrier signal is fed to pin 11 and
through a limiter amplifier before it is demodulated. This
achieves high sensitivity and high AM suppression. The
limiter amplifier consists of seven internal AC-coupled
stages, minimizing the DC offset.
The FM-PLL demodulator consists of an RC-oscillator,
loop filter and phase detector. The oscillator frequency is
locked on the FM intercarrier signal from the limiter
amplifier. As a result of this locking, the RC-oscillator is
frequency-modulated.
The modulating signal voltage (AF signal) is used to
control the oscillator frequency. By this, the FM-PLL
operates as an FM demodulator.
The audio frequency amplifier with internal feedback is
designed for high gain and high common mode rejection.
The low-level AF signal output from the FM-PLL
demodulator is amplified and buffered in a low-ohmic
audio signal output stage (pin 9). An external decoupling
capacitor on pin 10 removes the DC voltage from the audio
amplifier input.
By using the sound mute switch (pin 5) the AF amplifier is
set to mute state.

VCO and travelling wave divider

The VCO operates with a symmetrically-connected
reference LC-circuit, operating at double vision carrier
frequency. Frequency control is performed by an internal
varicap diode. The voltage to set the VCO frequency to the
actual frequency of double vision carrier frequency, is also
amplified and converted for the AFC output current.
The VCO signal is divided-by-two in a travelling wave
divider, which generates two differential output signals

not exceed the AF output signal of nominally 0.35 V for THD = 0.1% (Rx = 4.7 kΩ provides −6 dB amplification).

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

“IC Package Databook”

our

(order code 9398 652 90011).

DIP

SOLDERING BY DIPPING OR BY WAVE
The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). 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.

R

EPAIRING SOLDERED JOINTS

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.

SO

REFLOW SOLDERING
Reflow soldering techniques are suitable for all SO

packages.

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.

AVE SOLDERING

W
Wave soldering techniques can be used for all SO

packages if the following conditions are 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.

• The package footprint must incorporate solder thieves at
the downstream end.

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.

EPAIRING SOLDERED JOINTS

R
Fix the component by first soldering two diagonally-

opposite 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.

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.
