Single/multistandard VIF/SIF-PLL and
FM-PLL/AM demodulators

TDA9817; TDA9818

FUNCTIONAL DESCRIPTION

The integrated circuit comprises the functional blocks as
shown in Fig.1:

• Vision IF amplifier and VIF AGC detector

• Tuner AGC

• Frequency Phase Locked Loop detector (FPLL)

• VCO, Travelling Wave Divider (TWD) and AFC

• Video demodulator and amplifier

• SIF amplifier and SIF AGC

• Single reference QSS mixer

• AM demodulator

• FM-PLL demodulator

• AF (Audio Frequency) signal processing

• Internal voltage stabilizer.

Vision IF amplifier and VIF AGC detector

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

The AGC detector generates the required VIF gain control
voltage for constant video output by charging/discharging
the AGC capacitor. Therefore for negative video
modulation the sync level and for positive video
modulation the peak white level of the video signal is
detected. In order to reduce the reaction time for positive
modulation, where a very large time constant is needed,
an additional level detector increases the discharging
current of the AGC capacitor (fast mode) in the event of a
decreasing VIF amplitude step. The additional level
information is given by the black-level detector voltage.

Tuner AGC

The AGC capacitor voltage is converted to an internal IF
control signal, and is fed to the tuner AGC to generate the
tuner AGC output current at pin TAGC (open-collector
output). The tuner AGC takeover point can be adjusted at
pin TADJ. This allows to match the tuner to the SAW filter
in order to achieve the optimum IF input level.

Frequency Phase Locked Loop detector (FPLL)

The VIF-amplifier output signal is fed into a frequency
detector and into a phase detector 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. 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 frequency detector or phase
detector is converted into a DC voltage via the loop filter,
which controls the VCO frequency. In the event of positive
modulated signals the phase detector is gated by
composite sync in order to avoid signal distortion for
overmodulated VIF signals.

VCO, Travelling Wave Divider (TWD) and AFC

The VCO operates with a resonance circuit (with L and C
in parallel) at double the PC frequency. The VCO is
controlled by two integrated variable capacitors.
The control voltage required to tune the VCO from its
free-running frequency to actually double the PC
frequency is generated by the frequency-phase detector
(FPLL) and fed via the loop filter to the first variable
capacitor. This control voltage is amplified and additionally
converted into a current which represents the AFC output
signal. At centre frequency the AFC output current is equal
to zero.

For TDA9818: the VCO centre frequency can be
decreased (required for L accent standard) by activating
an additional internal capacitor. This is achieved by using
the L accent switch. In this event the second variable
capacitor can be controlled by a variable resistor at the L
accent switch for setting the VCO centre frequency to the
required L accent value.

The oscillator signal is divided by 2 with a TWD which
generates two differential output signals with a 90 degree
phase difference independent of the frequency.

Video demodulator and amplifier

The video demodulator is realized by a multiplier which is
designed for low distortion and large bandwidth. The vision
IF input signal is multiplied with the ‘in phase’ signal of the
travelling wave divider output. In the demodulator stage
the video signal polarity can be switched in accordance
with the TV standard.

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 for B/G and
L standard. The standard dependent level shift in this
stage delivers the same sync level for positive and
negative modulation. The video output signal at V

o(vid)

is

1.1 V (p-p) for nominal vision IF modulation, in order to
achieve 1 V (p-p) at sound trap output.

SIF amplifier and SIF AGC

The sound IF amplifier consists of two AC-coupled
differential amplifier stages. Each differential stage
comprises a controlled feedback network provided by
emitter degeneration.

The SIF AGC detector is related to the SIF input signal
(average level of AM or FM carrier) and controls the SIF
amplifier to provide a constant SIF signal to the
AM demodulator and single reference QSS mixer.
At L standard (AM sound) the SIF AGC reaction time is set
to ‘slow’ for nominal video conditions. But with a
decreasing VIF amplitude step the SIF AGC is set to ‘fast’
mode controlled by the VIF AGC detector. In FM mode this
reaction time is always ‘fast’.

Single reference QSS mixer

The single reference QSS mixer is realized by a multiplier.
The SIF amplifier output signal is fed to the single
reference QSS mixer and converted to intercarrier
frequency by the regenerated picture carrier (VCO).
The mixer output signal is fed via a high-pass for
attenuation of the video signal components to the output
pin 12. With this system a high performance hi-fi stereo
sound processing can be achieved.

For a simplified application without a sound IF SAW filter
the single reference QSS mixer can be switched to the
intercarrier mode by connecting pin 24 to ground. In this
mode the sound IF passes the vision IF SAW filter and the
composite IF signal is fed to the single reference QSS
mixer. This IF signal is multiplied with the 90 degree TWD
output signal for converting the sound IF to intercarrier
frequency. This composite intercarrier signal is fed to the
output pin 12, too. By using this quadrature detection, the
low frequency video signals are removed.

AM demodulator

The AM demodulator is realized by a multiplier.
The modulated SIF amplifier output signal is multiplied in
phase with the limited (AM is removed) SIF amplifier
output signal. The demodulator output signal is fed via an
integrated low-pass filter for attenuation of the carrier
harmonics to the AF amplifier.

FM-PLL demodulator

The FM-PLL demodulator consists of a limiter and an
FM-PLL. The limiter provides the amplification and
limitation of the FM sound intercarrier signal. The result is
high sensitivity and AM suppression. The amplifier

consists of 7 stages which are internally AC-coupled in
order to minimize the DC offset.

Furthermore the AF output signal can be muted by
connecting a resistor between the limiter input pin 13 and
ground.

The FM-PLL consists of an integrated relaxation oscillator,
an integrated loop filter and a phase detector.
The oscillator is locked to the FM intercarrier signal, output
from the limiter. As a result of locking, the oscillator
frequency tracks with the modulation of the input signal
and the oscillator control voltage is superimposed by the
AF voltage. The FM-PLL operates as an FM demodulator.

AF signal processing

The AF amplifier consists of two parts:

1. The AF pre-amplifier for FM sound 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 approximately 33 dB. The low-pass
characteristic of the amplifier reduces the harmonics of
the intercarrier signal at the sound output terminal
pin 9 at which the de-emphasis network for FM sound
is applied. An additional DC control circuit is
implemented to keep the DC level constant,
independent of process spread.

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 AM, FM
de-emphasis or mute state, controlled by the standard
switching voltage and the mute switching voltage.

Internal voltage stabilizer

The bandgap circuit internally generates a voltage of
approximately 1.25 V, independent of supply voltage and
temperature. A voltage regulator circuit, connected to this
voltage, produces a constant voltage of 3.6 V which is
used as an internal reference voltage.

Notes to the characteristics

1. Values of video and sound parameters are decreased at VP= 4.5 V.

2. This parameter is not tested during production and is only given as an application information for designing the
television receiver.

3. Loop bandwidth BL = 70 kHz (natural frequency fn= 12 kHz; damping factor d ≈ 3; calculated with sync level within
gain control range). Resonance circuit of VCO: Q0> 50; C

ext

= 8.2 pF ±0.25 pF; C

int

≈ 8.5 pF (loop voltage

approximately 2.7 V).

4. Temperature coefficient of external LC-circuit is equal to zero.

5. V

i(IF)(rms)

= 10 mV; ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture

video modulation.

6. V

iIF

signal for nominal video signal.

7. The leakage current of the AGC capacitor should not exceed 1 µA at B/G standard respectively 10 nA current at
L standard. Larger currents will increase the tilt.

8. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 16). B = 5 MHz weighted
in accordance with

“CCIR 567”

.

9. The intermodulation figures are defined:

; α

1.1

value at 1.1 MHz referenced to black/white signal;

; α

3.3

value at 3.3 MHz referenced to colour carrier.

10. Measurements taken with SAW filter K3953 (sound carrier suppression: 40 dB); loop bandwidth BL = 70 kHz:
a) Modulation VSB; sound carrier off; f

video

> 0.5 MHz.

b) Sound carrier on; SIF SAW filter K9453; f

video

= 10 kHz to 10 MHz.

11. Response speed valid for a VIF input level range of 200 µVupto70mV.

12. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.7. The AFC-steepness can be changed by the resistors at pin 17.

13. Depending on the ratio ∆C/C0 of the LC resonant circuit of VCO (Q0> 50; see note 3; C0=C

int+Cext

).

14. Source impedance: 2.3 kΩ in parallel to 12 pF (SAW filter); fIF= 38.9 MHz.

15. Without using an SIF SAW filter the mixer can be switched to intercarrier mode by connecting pin 23 and/or pin 24
to ground. In this mode the SIF passes the VIF SAW filter and IF intercarrier levels are depending on the sound shelf
of the VIF SAW filter. The intercarrier output signal at pin 12 can be calculated by the following formula taking into
account the video output signal at pin 16 (V

o(video)(p-p)

= 1.1 V typical) as a reference:

with = correction term for RMS value,

= sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB,

6 dB = correction term of internal circuitry
and ±3 dB = tolerance of video output and intercarrier output amplitude V

o(rms)

.

16. Input level for second IF from an external generator with 50 Ω source impedance. AC-coupled with 10 nF capacitor,
f

mod

= 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF/SIF input signal is not permitted. Pins 5 and 4
have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at
50 µs de-emphasis at pin 9 (modulator pre-emphasis has to be activated). The FM demodulator steepness
∆V

o(AF)

/∆fAF is positive.

a) Second IF input level 10 mV (RMS).

17. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV (RMS) (Rx=0Ω). By using
Rx= 470 Ω the AF output signal is attenuated by 6 dB (250 mV RMS). For handling a frequency deviation of more
than 53 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 with Rx= 470 Ω.

18. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.

19. For all S/N measurements the used vision IF modulator has to meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees.
b) QSS AF performance, measured with the television demodulator AMF2 (audio output, weighted S/N ratio) better

than 60 dB (deviation 27 kHz) for 6 kHz sine wave black-to-white video modulation.

c) Picture-to-sound carrier ratio; PC/SC1= 13 dB (transmitter).

20. The PC/SC1 ratio is calculated as the addition of TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio. This
PC/SC1 ratio is necessary to achieve the S/NW values as noted. A different PC/SC1 ratio will change these values.

21. Measurements taken with SAW filter K3953 for vision IF (suppressed sound carrier) and K9453 for sound IF
(suppressed picture carrier). Input level V

i(SIF)(rms)

= 10 mV, 27 kHz (54% FM deviation).

22. Measurements taken with SAW filter G1962 (sound shelf: 20 dB) for vision and sound IF. Pin 23 and/or pin 24 has
to be connected to ground for switching the single reference QSS mixer to intercarrier mode.

23. Measurements taken with SAW filter K9453 (Siemens) for AM sound IF (suppressed picture carrier).

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”

(order code 9398 652 90011).

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.

Repairing 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.
