FUNCTIONAL DESCRIPTION OF VIDEO PROCESSOR Vision IF amplifier
The vision IF amplifier can demodulate signals with positive and negative modulation. The PLL demodulator is completely
alignment-free.
The VCO of the PLL circuit is internal and the frequency is fixed to the required value by using the clock frequency of the
µ
-Controller/Teletext decoder as a reference. The setting of the various frequencies is made by the controlling software in
subaddress 27H (33.9 MHz for system L’ and 38.9
MHz for all other systems). Because of the internal VCO, the IF circuit
has a high immunity to EMC interference.
1. IF demodulator and audio amplifier
The FM demodulator is realised as a narrow band PLL with external loop filter, which provides the necessary selectivity
withoutusing an extra bandpassfilter.To obtain good selectivityalinearphasedetector and aconstantinputsignalampli-
tude are required. For this reason the intercarrier signal is internally supplied to the demodulator via a gain controlled
amplifier and AGC circuit. The nominal frequency of the demodulator is set via a gain controlled amplifier and AGC circuit.
The nominal frequency of the demodulator is tuned to the required frequency (5.5 / 6.0 / 6.5 MHz) by means of a calibra-
tion circuit which uses the clock frequency of the microcontroller as a reference. Selection of the required frequency is
done by the controlling software.
Video switches
The video switch has one input for an external CVBS or Y/C signal. The selected CVBS signal can be supplied to pin 38,
the IF video output. The selection between both signals is realised by the controlling software in subaddress 22H.
The video ident circuit is connected to the selected signal. This ident circuit is independent of the synchronisation.
Synchronisation circuit
The IC contains separator circuits for the horizontal and vertical sync pulses and a data-slicing circuit which extracts the
digital teletext data from the analogue signal.
The horizontal drive signal is obtained from an internal VCO which is running at a frequency of 25 MHz. This oscillator is
stabilised to this frequency by using a 12 MHz signal coming from the reference oscillator of the
µ
-Controller/Teletext
decoder.
Thehorizontal drive isswitchedonand off via thesoftstart/stopprocedure. This function isrealised by meansof variation
of the TON of the horizontal drive pulses.
FUNCTIONAL DESCRIPTION

FUNCTIONAL DESCRIPTION
The vertical synchronisation is realised by means of a divider circuit. The vertical ramp generator needs an external resistor
and capacitor. For the vertical drive a differential output current is available. The outputs are DC coupled to the vertical output
stage.
The following geometry parameters can be adjusted:
•
Horizontal shift
•
Vertical amplitude
•
Vertical slope
•
S-correction
•
Vertical shift
Chroma and luminance processing
The chroma band-pass and trap circuits (including the SECAM cloche filter) are realised by means of gyrators and are tuned to
therightfrequencybycomparing thetuningfrequency withthereference frequencyofthe colourdecoder. Theluminance delay
line and the delay cells for the peaking circuit are also realised with gyrators. The circuit contains a black stretcher function
which corrects the black level for incoming signals which have a difference between the black level and the blanking level.
Colour decoder
The ICs can decode PAL, NTSC and SECAM signals. The PAL/NTSC decoder does not need external reference crystals but
hasan internalclock generatorwhichis stabilisedtothe requiredfrequency byusingthe 12MHz clocksignalfrom thereference
oscillator of the
µ
-Controller/Teletextdecoder.
The Automatic Colour Limiting (ACL) circuit (switchable via the ACL bit in subaddress 2OH) prevents oversaturation occurring
when signals with a high chroma-to-burst ratio are received. The ACL circuit is designed such that it only reduces the chroma
signal and not the burst signal. This has the advantage that the colour sensitivity is not affected by this function.
SOFTWARE CONTROL
The CPU communicates with the peripheral functions using Special function Registers (SFRS) which are addressed as RAM
locations. The registers for the Teletext decoder appear as normal SFRs in the
µ
-Controller memory map and are written to
these functions by using a serial bus. This bus is controlled by dedicated hardware which uses a simple handshake system for
software synchronisation.
For compatibility reasons and possible re-use of software blocks, the TV processor is controlled by I2C bus. The TV processor
control registers cannot be read. Only the status registers can be read ( Read address 8A ).
The SECAM decoder contains an auto-calibrating PLL demodulator which has two references, via the divided 12 MHz refer-
ence frequency (obtained from the
µ
-Controller) which is used to tune the PLL to the desired free-running frequency and the
bandgap reference to obtain the correct absolute value of the output signal. The VCO of the PLL is calibrated during each ver-
tical blanking period, when the IC is in search or SECAM mode.
The base-band delay line (TDA 4665 function) is integrated. This delay line is also active during NTSC reception, to obtain a
good suppression of cross colour effects. The demodulated colour difference signals are internally supplied to the delay line.

RGB output circuit and black-current stabilisation
IntheRGB control circuit the signal is controlledoncontrast,brightness and saturation. The ICs have a linearinputforexternal
RGB signals. The signals for OSD and text are internally supplied to the control circuit. The output signal has an amplitude of
about 2 Volts black-to-white at nominal input signals and nominal settings of the various controls.
To obtain an accurate biasing of the picture tube the 'Continuous Cathode Calibration’system has been included in these ICs.
A black level off set can be made with respect to the level which is generated by the black current stabilisation system. In this
way different colour temperatures can be obtained for the bright and the dark part of the picture.
The black current stabilisation system checks the output level of the 3 channels and indicates whether the black level of the
highest output is in a certain window or below or above this window. This indication is read from the status byte 01 and is used
for automatic adjustment of the Vg2
voltage during the production of the TV receiver.
During switch-off of the TV receiver a fixed beam current is generated by the black current control circuit. This current ensures
that the picture tube capacitance is discharged. During the switch-off period the vertical deflection is placed in an overscan
position so that the discharge is not visible on the screen.
2. IF
The TDA9361/TDA9381 has an alignment free IF PLL demodulator. The fully integrated oscillator is automatically calibrated,
using the 12 MHz crystal as a frequency reference. The IF frequency is simply set in TV-Processor by I2C bus.
TheAFCinformation is available via I2Cbusfromthe TV-Processor status bytes. Thecontrollingsoftwareuses this information
for tuner frequency tracking ( automatic following ). The AFC window is typically 125Khz wide. The minimum frequency step of
the tuner is 62.5 kHz.
This AFC function is disabled when a program is tuned using the direct frequency entry or after fine tuning adjustment. There-
fore it is recommended to tune a channel with the TV search function ( manual or ATSS ) or by using the direct channel entry to
enable the Automatic Frequency Control.

FUNCTIONAL DESCRIPTION

ForSECAM L and L’the TDA9361/TDA9381 is switched to positive modulation via I2C bus. SECAM L’ transmission onlyoccur
in VHF band I and have their picture and sound carrier interchanged, compared to SECAM L and PAL B/G channels. For
SECAM L’the picture carrier is situated at 33.9 MHz and the AM sound carrier at 40.40 MHz. The IF PLL reference is tuned
from 38.9 to 33.9 MHz, this is done via I2C Bus and the SIF filter is switched from channel 2 to channel 1; this is done by pin 4
of TDA 9361.
The tuner AGC time constant is slower for positive than for negative modulation, because the TDA9361 reduces its AGC cur-
rent.Tomake the AGC time constant even sloweranextraseries resistor R103 is added. To preventIFoverloadwhen jumping
from a very strong transmitter to a weak transmitter a diode D101 has been added
************************************************************************************************************************************************
The SAW filter ( SF1 ) has a double Nyquist slope at 38.9 MHz and 33.9 MHz needed for this multistandard application.
The disadvantage of this choice is that a 5.5 MHz trap filter ( Z501 ) is needed to suppress the residual sound carrier in the
video for B/G signals.
************************************************************************************************************************************************
3. Source switching
Video :
The TDA9361/TDA9381 has only one external video input. The SCART video in pin (#20) is connected to the front RCA video
input.
The controlling software via I2C bus selects the signal source :
- Video signal from tuner ( Pin 40 ).
- External video.
- External SVHS from SCART.
The sound source switching is done in the video processor part and in the AM demodulator by the
µ
-Controller via I2C
bus.
The video processor pin 28 has multiple functions and provides in this application
- Deemphasis time constant
- Audio monitor output
- External AM input
- Deemphasis time constant : The time constant is given by the capacitor C504, needed to obtain the 54
µ
s time constant
for standard PAL signal.
- Audio monitor output : the nominal output signal is 500 mVrms, for all standards. The signal is also internally connected
throughtotheaudioswitch.ThissignalisnotcontrolledbythevolumesettingandcanbeusedforSCARTaudiooutput.
The signal is buffered to avoid influencing the deemphasis time constant and to adjust the output level.
- External AM input : By software the deemphasis pin can be converted into an input pin. External AM signal for SECAM
L/L’ is directly connected to this pin. In this configuration the FM sound is internally muted, DC level remains at 3Vdc.
An external sound signal of 500mVrms is applied to pin 35 via a coupling capacitor. The input impedance of this pin is
25K
Ω
typical. Switching between internal FM, external AM or external audio from SCART is controlled internally by soft-
ware.

Fast R, G, B insertion : The external R, G, B insertion needs a fast switching and cannot be controlled by the software (
instruction cycle of 1
µ
sec ). The fast switching pin 16 of SCART is directly connected to the TV processor pin 45 ( Fast
blankinginput ). The display is synchronised with the selected videosource, i.e. toget stable R,G, B signal insertion they
must be synchronised with the selected video source.

µ
-Controller I/O pin configuration and function
The I/O pins of the
µ
-Controller can be configured in many ways. All port functions can be individually programmed by the con-
trolling software.
Each I/O port pin can be individually programmed in these configurations :
Open drain
In this mode, the port can function as input and output. It requires an external pull-up resistor. The maximum allowable supply
voltage for this pull up resistor is +5V.
So in this mode it is possible to interface a 5 Volt environment like I2C while the
µ
-Controller has a 3.3 Volt supply.
Push-Pull
Thepush pullmodecan beusedfor outputonly.Both sinkingandsourcing isactive, whichleads tosteep slopes.The levelsare
0 and Vddp, the supply voltage 3.3Volts.
High impedance
This mode can be used for input only operation of the port.
Special port for LED
Pin10 and 11 have the same functionality as the general I/O pins but in addition, their current source and sink capacity is 8 mA
instead of 4 mA. These pins are used for driving LED’s via a series current limiting resistor.

5. SECAM L/L’ sound switching circuit.
The microcontroller pin 4 is a three levels output. The voltage and configuration of this port is described below :
In FM mode the microcontroller is internally grounded to pin 4. The TDA9830 output is muted
6. Sound amplification
Thedevice TDA7267A is amonoaudio amplifier inpowerDIPpackage specially designed forTVapplication. Thanks to thefully
complementary output configuration the device delivers a rail to rail voltage swing without need of bootstrap capacitors. No
external heat sink is needed as the Cu ground plane of the PCB is used as heat dissipation.
7. Vertical deflection
The vertical driver circuit is a bridge configuration. The deflection coil is connected between the output amplifiers, which are
driven in phase opposition. The differential input circuit is voltage driven. The input circuit is especially intended for direct con-
nection to driver circuits which deliver symmetrical current signals, but is also suitable for asymmetrical currents. The output
current of these devices is converted to voltages at the input pins via resistors R350 and R351. The differential input voltage is
compared with the output current through the deflection coils measured as voltage across R302, which provides internal feed-
back information. The voltage across R302 is proportional to the output current.
Flyback voltage
Theflybackvoltageis determined by an additional supply voltage V
fb
.Theprincipleof operation with two supply voltages (class
G) makes it possible to fix the supply voltage Vp optimum for the scan voltage and the second supply voltage V
fb
optimum for
the flyback voltage. Using this method, very high efficiency is achieved. The supply voltage V
fb
is almost totally available as fly-
back voltage across the coil, this being possible due to the absence of a coupling capacitor.
Protection
The output circuit has protection circuits for :
- Too high die temperature
- overvoltage of output stage A
Guardcircuit
The guard signal is not used by the TDA9361/ TDA9381 to blank the screen in case of a fault condition.
Damping resistor
For HF loop stability a damping resistor (R305) is connected across the deflection coil.
