Single standard VIF-PLL with QSS-IF and
FM-PLL demodulator

TDA9808

FUNCTIONAL DESCRIPTION

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

1. Vision IF amplifier and VIF AGC detector

2. Tuner AGC

3. Frequency Phase Locked Loop (FPLL) detector

4. Voltage Controlled Oscillator (VCO), Travelling Wave
Divider (TWD) and AFC

5. Video demodulator and amplifier

6. SIF amplifier and SIF AGC

7. Single reference QSS mixer

8. FM-PLL demodulator

9. Audio Frequency (AF) signal processing

10. 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 synchronisation level of the video signal is
detected.

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 (FPLL) detector

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 the frequency detector or the
phase detector is converted to a DC voltage via the loop
filter, which controls the VCO frequency.

VCO, Travelling Wave Divider (TWD) and AFC

The VCO operates with a resonance circuit (with L and C
in parallel) at double the Picture Carrier (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 double the PC frequency
is generated by the frequency-phase detector of the 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 the
centre frequency the AFC output current is equal to zero.

The oscillator signal is divided-by-two 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.

The demodulator output signal is fed to the video amplifier
via an integrated low-pass filter for attenuation of the
carrier harmonics. 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 output
signal at pin V

o(vid)

is 1.35 V (p-p) for nominal vision IF

modulation. Noise clipping is provided.

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 FM carrier) and controls the SIF amplifier
to provide a constant SIF signal to the single reference
QSS mixer.

Philips Semiconductors Product specification

FM-PLL demodulator

TDA9808

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 filter for
attenuation of the video signal components to the output
pin 10. With this system a high performance hi-fi stereo
sound processing can be achieved.

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 11 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 10. 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 FM or
mute state, controlled by 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. Level headroom for input level jumps during gain control setting.

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

4. 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

see Table 3; C

int

≈ 8.5 pF (loop voltage approximately

2.7 V).

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

signal for nominal video signal.

8. The leakage current of the AGC capacitor should not exceed 100 nA at M, N standard. Larger currents will increase
the tilt.

9. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 9). B = 5 MHz weighted
in accordance with

“CCIR 567”

.

10. The intermodulation figures are defined:

11. Measurements taken with SAW filter M3951 (sound carrier suppression: 32 dB); loop bandwidth BL = 70 kHz:
a) Modulation VSB; sound carrier off; f

b) Sound carrier on; SIF SAW filter M9352; f

video

= 10 kHz to 10 MHz.

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

13. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.10. The AFC-steepness can be changed by the resistors at pin 13.

14. Depending on the ratio ∆C/C0 of the LC resonant circuit of VCO (Q0> 50; see note 4; C0=C

int+Cext

).

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

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

mod

= 400 Hz, 25 kHz (50% FM deviation) of audio reference. A VIF/SIF input signal is not permitted. Pins 5 and 17
have to be connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at
75 µs de-emphasis (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 at de-emphasis circuitry with an FM deviation of 25 kHz (f

mod

= 400 Hz) 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 (22 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 25 kHz) for 6 kHz sine wave black-to-white video modulation.

c) Picture-to-sound carrier ratio; PC/SC1= 7 dB (transmitter).

20. The PC/SC1 ratio is calculated as the addition to TV transmitter PC/SC1 ratio and SAW filter PC/SC1 ratio.
This PC/SC1 ratio is necessary to achieve the S/N

W(audio)

values as noted. A different PC/SC1 ratio will change these

values.

21. Measurements taken with SAW filter M3951 for vision IF (suppressed sound carrier, minimum 25 dB) and M9352 for
sound IF (suppressed picture carrier). Input level V

i(SIF)(rms)

= 10 mV, 25 kHz (50% FM deviation). Measurements in

SOLDERING
Introduction

This text gives a 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 IC

packages. Wave soldering is often preferred when
through-hole and surface mount components are mixed on
one printed-circuit board. However, wave soldering is not
always suitable for surface mount ICs, or for printed-circuit
boards with high population densities. In these situations
reflow soldering is often used.

Through-hole mount packages

S

OLDERING BY DIPPING OR BY SOLDER WAVE

The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints 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.

M

ANUAL SOLDERING

Apply the soldering iron (24 V or less) to the lead(s) of the
package, either 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.

Surface mount packages

REFLOW SOLDERING
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 methods exist for reflowing; for example,
infrared/convection 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 230 °C.

W

AVE SOLDERING

Conventional single wave soldering is not recommended
for surface mount devices (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.

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.

• For packages with leads on four sides, the footprint must
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.

M

ANUAL 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.

Suitability of IC packages for wave, reflow and dipping soldering methods

Notes

1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

.

2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.

3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).

4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.

5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
