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.

FUNCTIONAL DESCRIPTION

The integrated circuit comprises the functional blocks as

shown in Fig.1:

• Vision IF amplifier and input switch

• Tuner and VIF-AGC

• Frequency Phase Locked Loop detector (FPLL)

• VCO, Travelling Wave Divider (TWD) and AFC

• Video demodulator and amplifier

• Video buffer

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. 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. At centre frequency the AFC output current is equal

to zero.

• SIF amplifier and AGC

• Single reference QSS mixer

• AM demodulator

• Internal voltage stabilizer and ¹⁄₂V_P-reference.

Vision IF ampliﬁer and input switch

The vision IF amplifier consists of three AC-coupled

differential amplifier stages. Each differential stage

comprises a feedback network controlled by emitter

degeneration. The first differential stage is extended by

two pairs of emitter followers to provide two IF input

channels. The VIF input can be selected by pin 30.

Tuner and VIF-AGC

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 (open-collector output). The

tuner AGC takeover point can be adjusted. This allows the

tuner and the SAW filter to be matched to achieve the

optimum IF input level.

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 AGC detector charges/discharges the AGC capacitor

to the required voltage for setting of VIF and tuner gain in

order to keep the video signal at a constant level.

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.

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 is 1 V (p-p)

for nominal vision IF modulation.

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

Video buffer

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.

For an easy adaption of the sound traps an operational

amplifier with internal feedback is used in the event of B/G

and L standard. This amplifier is featured with a high

bandwidth and 7 dB gain. The input impedance is adapted

for operating in combination with ceramic sound traps. The

output stage delivers a nominal 2 V (p-p) positive video

signal. Noise clipping is provided.

Internal voltage stabilizer and ¹⁄₂V_P-reference

SIF ampliﬁer and AGC

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.

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 signals

(average level of AM or FM carriers) and controls the SIF

amplifier to provide a constant SIF signal to the AM

demodulator and single reference QSS mixer. 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 also set to ‘fast’

controlled by the standard switch.

For the audio output signal the constant reference voltage

cannot be used because large output signals are required.

Therefore this signal refers to half the supply voltage to

achieve a symmetrical headroom. For ripple and noise

attenuation the ¹⁄₂V_Pvoltage has to be filtered via a

low-pass filter by using an external capacitor together with

an integrated resistor (f_g= 5 Hz). For a fast setting to¹⁄₂V_P

an internal start-up circuit is added.

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 20. With this

system a high performance hi-fi stereo sound processing

can be achieved.

Notes to the characteristics

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

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

television receiver.

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

4. Loop bandwidth BL = 75 kHz (natural frequency f_n= 11 kHz; damping factor d ≈ 3.5; 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).

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

6. V_{i IF}= 10 mV RMS; ∆f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture

video modulation.

7. V_{i IF}signal for nominal video signal.

8. Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 75 kHz:

a) Modulation VSB; sound carrier off; f_video> 0.5 MHz.

b) Sound carrier on; SIF SAW filter L9453; f_video= 10 kHz to 10 MHz.

9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 2 V (p-p), in event of

CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 Ω resistor must be connected from

output to input (from pin 21 to pin 22).

10. 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.

11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 10). B = 5 MHz weighted

in accordance with “CCIR 567”.

12. The intermodulation figures are defined:

V₀at 4.4 MHz

α_1.1= 20 log

+ 3.6dB; α_1.1value at 1.1 MHz referenced to black/white signal;

-------------------------------------

V₀at 1.1 MHz

V₀at 4.4 MHz

α_3.3= 20 log

; α_3.3value at 3.3 MHz referenced to colour carrier.

-------------------------------------

V₀at 3.3 MHz

13. Response speed valid for a VIF input level range of 200 µV up to 70 mV.

14. 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 23.

15. Depending on the ratio ∆C/C₀of the LC resonant circuit of VCO (Q₀> 50; see note 4; C₀= C_int+ C_ext).

16. The V_{o QSS}output (pin 20) is analysed by a test demodulator TDA9820. The S/N of this equipment should be higher

than 60 dB, related to a deviation of ±27 kHz, in accordance with “CCIR 468-4”.

17. 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).

18. Measurements taken with SAW filter G3962 (Siemens) for vision IF (suppressed sound carrier) and G9350

(Siemens) for sound IF (suppressed picture carrier). Input level V_{i SIF}= 10 mV RMS, 27 kHz (54% FM deviation).

19. The PC/SC ratio at pins 1 and 2 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/N (W) values as noted. A different PC/SC ratio will change

these values.

20. Measurements taken with SAW filter L9453 (Siemens) for AM sound IF (suppressed picture carrier).

21. The input voltage has to be V_i> 2.8 V or open-circuit.

Multistandard VIF-PLL with QSS-IF and

AM demodulator

TDA9811

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.

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.

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.

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.
