Alignment-free multistandard vision and
FM sound IF-PLL demodulator

FUNCTIONAL DESCRIPTION

Figure 1 shows the simplified block diagram of the
integrated circuit. The integrated circuit comprises the
following functional blocks:

1. VIF amplifier

2. Tuner-AGC and VIF-AGC

3. VIF-AGC detector

4. Frequency Phase-Locked Loop (FPLL) detector

5. VCO and Travelling Wave Divider (TWD)

6. Digital acquisition help and AFC

7. Video demodulator and amplifier

8. Sound carrier trap

9. Intercarrier mixer

10. FM demodulator and acquisition help

11. Audio amplifier

12. Internal voltage stabilizer.

VIF amplifier

The VIF amplifier consists of three AC-coupled differential
amplifier stages. Each differential stage comprises a
feedback network controlled by emitter degeneration.

Tuner-AGC and VIF-AGC

The AGC capacitor voltage is converted to an internal VIF
gaincontrol signal, and is fedto the tuner AGC togenerate
the tuner AGC output current at pin TAGC (open-collector
output). The tuner AGC takeover point can be adjusted
with R
filter in order to achieve the optimum IF input level.

VIF-AGC detector

The AGC detector generates the required VIF gain control
voltage for constant video output by charging or
discharging the AGC capacitor. Gain control is performed
by sync level detection. The newly developed AGC circuit
provides fast reaction time to cope with ‘aeroplane
fluttering’. The time constants for decreasing or increasing
gain are nearly equal.

. This allows the tuner to be matchedto the SAW

TOP

TDA9880T

After frequency lock-in the phase detector produces a DC
current proportional to the phase difference between the
VCO and the input signal. The DC current of either the
frequency detector or the phase detector is converted into
aDCvoltagevia the VIF-PLL filter, which controls the VCO
frequency.

VCO and Travelling Wave Divider (TWD)

The Resistor Capacitor (RC) VCO operates as an
integrated relaxation oscillator atdouble the picture carrier
frequency.The control voltage required totunethe VCO to
actually double the picture carrier frequency is generated
by the FPLL detector and fed via the loop filter to the VCO
control input terminal.

The oscillator signal is divided-by-two with a TWD which
generatestwo differential output signals witha 90 degrees
phase difference independent of the frequency.

Digital acquisition help and AFC

The integrated relaxation oscillator has a very wide
frequency range from approximately 30 to 70 MHz (after
the TWD). To prevent false locking of the FPLL and with
respect to the catching range of the frequency detector of
maximum ±2.5 MHz, the Digital Acquisition Help (DAH)
provides current into the loop filter until the VCO is in a
frequency window of ±2.3 MHz around the wanted VIF
frequency. In this case the analog operating FPLL willlock
the VCO to the VIF carrier and the acquisition help does
not provide any current to the loop filter.

The principle of the digital acquisition help is as follows:
the VCO is connected to a downcounter, which is preset
depending on the required VIF frequency. The counting
time, as well as the counter control, is derived from a
4 MHz reference signal. This signal can be supplied from
the internal 4 MHz crystal oscillator or from the 4 MHz
reference oscillator of an external tuning system.
The counting result after a counting cycle corresponds to
the actual VCO frequency.

The digital AFC is also derived from the counting result
after a counting cycle by digital-to-analog converting the
last four bits of the counter.

Frequency Phase-Locked Loop (FPLL) detector

The VIF amplifier output signal is fed into a Frequency
Detector(FD) and into a PhaseDetector (PD) via a limiting
amplifier. During acquisition the frequency detector
produces a DC current proportional to the frequency
difference between the input and the VCO signal.

Video demodulator and amplifier

The video demodulator is realized by a multiplier which is
designedforlowdistortionandlargebandwidth.Thevision
IF input signal is multiplied with the ‘in phase’ signal of the
travelling wave divider output.

Philips Semiconductors Product specification

Alignment-free multistandard vision and
FM sound IF-PLL demodulator

The demodulator output signal is fed via an integrated
low-pass filter for attenuation of the carrier harmonics to
the video amplifier. The video amplifier is realized by an
operational amplifier with internal feedback and high
bandwidth. A low-pass filter is integrated to achieve an
attenuation of the carrier harmonics. The video signal of

1.1 V (p-p) for nominal vision IF modulation is fed
internally to the integrated sound carrier trap as well as to
the VIF-AGC detector. The second stage of the video
amplifier converts and amplifies the differential output
signal from the sound carrier trap to the single-ended
CVBS output signal at pin 13 with a 2 V (p-p) amplitude.

Noise clipping is provided. Furthermore the trap can be
bypassed by the implemented input switch of the second
amplifier stage, forced by connecting pin 12 to ground.

Sound carrier trap

The sound carrier trap consists of a reference filter, a
phase detector and the sound trap itself.

A sound carrier reference signal is fed into the reference
low-pass filter and is shifted by a nominal 90 degrees.
The phasedetectorcomparestheoriginalreferencesignal
with the signal shiftedby the reference filter and produces,
at the external capacitor CTR, a DC voltage by charging or
discharging the capacitor with a current proportional to the
phase difference between both signals, respectively to the
frequency error of the integrated filters. The DC voltage is
converted to currents which control the frequency position
of the reference filter and the sound trap.

The sound trap itselfis constructed of three separate traps
to realize sufficient suppression of the first and second
sound carrier. The right frequency position of the different
standards is set by the sound carrier reference signal.

Intercarrier mixer

The intercarrier mixer is realized by a multiplier, operating
inquadraturemodeforsuppressionoflowfrequencyvideo
signals. The VIF amplifier output signal is fed to the
intercarrier mixer and converted to an intercarrier
frequency by the regenerated 90 degree picture carrier
from the VCO. The mixer output signal is fed via a
band-pass filter and amplifier for attenuation of the high
frequency video signal components and carrier harmonics
to the output pin 11. The intercarrier signal is fed also to
the integrated FM demodulator.

TDA9880T

FM demodulator and acquisition help

The FM demodulator is realized as a narrow-band PLL
with external loop filter, which provides the necessary
selectivity. To achieve good selectivity, a linear phase
detector and constant input level are required. The
intercarrier signal from the intercarrier mixer is fed via a
gain controlled amplifier to the phase detector and it’s
output signal controls (via the loop filter) the integrated
relaxation oscillator. The possible frequency range is from
4 to 7 MHz. As a result of locking the oscillator frequency
tracks with the FM modulation of the input signal;
therefore,theoscillator control voltage is superimposed by
the AF voltage. In this way the FM-PLL operates as an
FM demodulator. The AF voltage is present at the loop
filter and is fed via a buffer with 0 dB gain to the audio
amplifier.

The digital acquisition help operates in the same way as
described in Section “Digital acquisition help and AFC”.

Audio amplifier

The audio amplifier consists of two parts:

1. The AF preamplifier is an operational amplifier with
internal feedback, high gain and high common mode
rejection. The AF voltage from the PLL demodulator,
by principle a small output signal, is amplified by
30 dB. A DC operating point control circuit (pin 6)
decouples the AF amplifier from the DC voltage of the
PLL. The low-pass characteristic of the amplifier
reduces the harmonics of the intercarrier signal at the
sound output terminal. If required, a de-emphasis
network can be realized by the amplifier output
resistance and an external capacitor.

2. The AF output amplifier (10 dB) provides the required
output level by a rail-to-rail output stage. This amplifier
makes use of an input selector for switching to mute
state, automatically controlled by the mute switching
voltage from the digital acquisition help in order to
avoid lock-in noise. During normal operation the
automatic audio mute function is not active.
Application of a 2.2 kΩ resistor between the
intercarrier output (pin 11) and ground will activate the
automatic audio mute function.

Internal voltage stabilizer

The band gap circuit internally generates a voltage of
approximately 2.4 V, independent of the supply voltage
and the temperature. Avoltage regulator circuit, controlled
by this voltage, produces a constant voltage of 3.55 V
which is used as an internal reference voltage.

19. For all S/N measurements the used vision IF modulator requires an incidental phase modulation for black-to-white
jump of less than 0.5 degrees.

= 10 mV (sync

“CCIR 468-4”

.

De-emphasis = 75 µs.

21. The PC/SC ratio is calculated as the addition of TV transmitter PC/SC ratio and SAW filter PC/SC ratio. This PC/SC
ratio is necessary to achieve the S/NW values as noted. A different PC/SC ratio will change these values.

22. Measured with an FM deviation of 25 kHz, the typical AF output signal is 500 mV (RMS). By using Rx=20kΩ the
AF output signal is attenuated by 6 dB, so 250 mV (RMS). For handling an FM deviation of more than 55 kHz the
AF output signal has to be reduced by using Rx in order to avoid clipping (THD < 1.5%). For an FM deviation up to
100 kHz an attenuation of 6 dB is recommended.

23. C

25. The reference input pin 15 is able to operate as a 1-pin crystal oscillator as well as an input terminal with external
reference signal, e.g. from the tuning system.

26. The value of Cxdetermines the accuracy of the resonance frequency of the crystal. It depends on the type of crystal
used.

SOLDERING
Introduction to soldering surface mount packages

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

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for
certainsurfacemountICs,butit is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.

Reflow soldering

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

Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.

Wave soldering

Conventional single wave soldering is not recommended
forsurfacemountdevices(SMDs)or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

TDA9880T

If wave soldering is used the following conditions must be
observed for optimal results:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

• Forpackageswithleadsonfoursides,thefootprintmust
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

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.

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.

Manual soldering

Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron 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.
