GENERAL DESCRIPTION
The TDA8360, TDA8361 and
TDA8362 are single-chip TV
processors which contain nearly all
small signal functions that are
required for a colour television
receiver. For a complete receiver the
following circuits need to be added:
a base-band delay line (TDA4661),
a tuner and output stages for audio,
video and horizontal and vertical
deflection.
Because of the different functional
contents of the ICs the set maker can
make the optimum choice depending
on the requirements for the receiver.
The TDA8360 is intended for simple
PAL receivers (all PAL standards,
including PAL-N and PAL-M are
possible).
The TDA8361 contains a PAL/NTSC
decoder and has an A/V switch.
For real multistandard applications
the TDA8362 is available. In addition
to the extra functions which are
available in the TDA8361, the
TDA8362 can handle signals with
positive modulation and it supplies
the signals which are required for the
SECAM decoder TDA8395.
The TDA8360 has the following
differences to the pinning:
Pin 6: external audio input not
connected
Pin 15: external CVBS input not
connected
Pin 16: chrominance and A/V switch
input not connected
Pin 27: hue control input not
connected.
TDA8361
The TDA8361 has the following
differences to the pinning:
Pin 1: only audio de-emphasis
Pin 27: only hue control
Pin 32: 4.43 MHz output for TDA8395
is not connected.
FUNCTIONAL DESCRIPTION
Video IF amplifier
The IF amplifier contains
3 AC-coupled control stages with a
total gain control range of greater
than 60 dB. The sensitivity of the
circuit is comparable with that of
modern IF ICs.
The reference carrier for the video
demodulator is obtained by means of
passive regeneration of the picture
carrier. The external reference tuned
circuit is the only remaining
adjustment of the IC.
In the TDA8362 the polarity of the
demodulator can be switched so that
the circuit is suitable for both positive
and negative modulated signals.
The AFC circuit is driven with the
same reference signal as the video
demodulator. To ensure that the
video content does not disturb the
AFC operation a sample-and-hold
circuit is incorporated; the capacitor
for this function is internal. The AFC
output voltage is 6 V.
The AGC detector operates on levels,
top sync for negative modulated and
top white for positive modulated
signals.The AGC detector time
constant capacitor is connected
externally. This is mainly because of
the flexibility of the application.
The time constant of the AGC system
during positive modulation
(TDA8362) is slow, this is to avoid any
visible picture variations. This,
however, causes the system to react
very slowly to sudden changes in the
input signal amplitude.
TDA8360; TDA8361; TDA8362
To overcome this problem a speed-up
circuit has been included which
detects whether the AGC detector is
activated every frame period. If,
during a 3-frame period, no action is
detected the speed of the system is
increased. When the incoming signal
has no peak white information (e.g.
test lines in the vertical retrace period)
the gain would be video signal
dependent. To avoid this effect the
circuit also contains a black level
AGC detector which is activated when
the black level of the video signal
exceeds a certain level.
The TDA8361 and TDA8362 contain
a video identification circuit which is
independent of the synchronization
circuit. Therefore search tuning is
possible when the display section of
the receiver is used as a monitor. In
the TDA8360 this circuit is only used
for stable OSD at no signal input. In
the normal television mode the
identification output is connected to
the coincidence detector, this applies
to all three devices. The identification
output voltage is LOW when no
transmitter is identified. In this
condition the sound demodulator is
switched off (mute function). When a
transmitter is identified the output
voltage is HIGH. The voltage level is
dependent on the frequency of the
incoming chrominance signal.

Sound circuit
The sound bandpass and trap filters
have to be connected externally. The
filtered intercarrier signal is fed to a
limiter circuit and is demodulated by
means of a PLL demodulator. The
PLL circuit tunes itself automatically
to the incoming signal, consequently,
no adjustment is required.
The volume is DC controlled. The
composite audio output signal has an
amplitude of 700 mV RMS at a
volume control setting of −6 dB. The
de-emphasis capacitor has to be
connected externally. The
non-controlled audio signal can be
obtained from this pin via a buffer
stage. The amplitude of this signal is
350 mV RMS.
The TDA8361 and TDA8362 external
audio input signal must have an
amplitude of 350 mV RMS. The
audio/video switch is controlled via
the chrominance input pin.
Synchronization circuit
The sync separator is preceded by a
voltage controlled amplifier which
adjusts the sync pulse amplitude to a
fixed level. The sync pulses are then
fed to the slicing stage (separator)
which operates at 50% of the
amplitude.
The separated sync pulses are fed to
the first phase detector and to the
coincidence detector. The
coincidence detector is used for
transmitter identification and to detect
whether the line oscillator is
synchronized. When the circuit is not
synchronized the voltage on the
peaking control pin (pin 14) is LOW
so that this condition can be detected
externally. The first PLL has a very
high static steepness, this ensures
that the phase of the picture is
independent of the line frequency.
The line oscillator operates at twice
the line frequency.
The oscillator network is internal.
Because of the spread of internal
components an automatic adjustment
circuit has been added to the IC.
The circuit compares the oscillator
frequency with that of the crystal
oscillator in the colour decoder. This
results in a free-running frequency
which deviates less than 2% from the
typical value.
The circuit employs a second control
loop to generate the drive pulses for
the horizontal driver stage.
X-ray protection can be realised by
switching the pin of the second
control loop to the positive supply line.
The detection circuit must be
connected externally. When the X-ray
protection is active the horizontal
output voltage is switched to a high
level. When the voltage on this pin
returns to its normal level the
horizontal output is released again.
The IC contains a start-up circuit for
the horizontal oscillator. When this
feature is required a current of 6.5 mA
has to be supplied to pin 36. For an
application without start-up both
supply pins (10 and 36) must be
connected to the 8 V supply line.
The drive signal for the vertical ramp
generator is generated by means of a
divider circuit. The RC network for the
ramp generator is external.
Integrated video filters
The circuit contains a chrominance
bandpass and trap circuit. The filters
are realised by means of gyrator
circuits and are automatically tuned
by comparing the tuning frequency
with the crystal frequency of the
decoder.
In the TDA8361 and TDA8362 the
chrominance trap is active only when
the separate chrominance input pin is
connected to ground or to the positive
supply voltage and when a colour
signal is recognized.
TDA8360; TDA8361; TDA8362
When the pin is left open-circuit the
trap is switched off so that the circuit
can also be used for S-VHS
applications.
The luminance delay line and the
delay for the peaking circuit are also
realised by means of gyrator circuits.
Colour decoder
The colour decoder in the various ICs
contains an alignment-free crystal
oscillator, a colour killer circuit and
colour difference demodulators.
The 90° phase shift for the reference
signal is achieved internally. Because
the main differences of the 3 ICs are
found in the colour decoder the
various types will be discussed.
TDA8360
This IC contains only a PAL decoder.
Depending on the frequency of the
crystals which are connected to the IC
the decoder can demodulate all PAL
standards. Because the horizontal
oscillator is calibrated by using the
crystal frequency as a reference the
4.4 MHz crystal must be connected to
pin 35 and the 3.5 MHz crystal to
pin 34. When only one crystal is
connected to the IC the other crystal
pin must be connected to the positive
supply rail via a 47 kΩ resistor. For
applications with two 3.5 MHz
crystals both must be connected to
pin 34 and the switching between the
crystals must be made externally.
Switching of the crystals is only
allowed directly after the vertical
retrace. The circuit will indicate
whether a PAL signal has been
identified by the colour decoder via
the saturation control pin.
When two crystals are connected to
the IC the output voltage of the video
identification circuit indicates the
frequency of the incoming
chrominance signal.

processors
The conditions are:
• Signal identified at
f
= 3.6 MHz; VO = 6 V
osc
• Signal identified at
f
= 4.4 MHz (or no colour);
osc
VO = 8 V.
This information can be used to
switch the sound bandpass filter and
trap filter.
TDA8361
This IC contains an automatic
PAL/NTSC decoder. The conditions
for connecting the reference crystals
are the same as for the TDA8360.
The decoder can be forced to PAL
when the hue control pin is connected
to the positive supply voltage via a
5kΩ or 10 kΩ resistor
(approximately). The decoder cannot
be forced to the NTSC standard. It is
also possible to see if a colour signal
is recognized via the saturation pin.
TDA8362
In addition to the possibilities of the
TDA8361, the TDA8362 can
co-operate with the SECAM add-on
decoder TDA8395.
The communication between the two
ICs is achieved via pin 32. The
TDA8362 supplies the reference
signal (4.43 MHz) for the calibration
system of the TDA8395, identification
of the colour standard is via the same
connection. When a SECAM signal is
detected by the TDA8395 the IC will
draw a current of 150 µA. When
TDA8362 has not identified a colour
signal in this condition it will go into
the SECAM mode, that means it will
switch off the R−Y and B−Y outputs
and increase the voltage level on
pin 32.
This voltage will switch off the
colour-killer in the TDA8395 and
switch on the R−Y and B−Y outputs of
the TDA8395. Forcing the system to
the SECAM standard can be
achieved by loading pin 32 with a
current of 150 µA. Then the system
manager in the TDA8362 will not
search for PAL or NTSC signals.
Forcing to NTSC is not possible.
For PAL/SECAM applications the
input signal for the TDA8395 can be
obtained from pin 27 (hue control)
when this pin is connected to the
positive supply rail via the 5 kΩ or
10 kΩ resistor. An external source
selector is required by the
TDA8395/TDA8362 combination for
PAL/SECAM/NTSC applications.
RGB output circuit
The colour difference signals are
matrixed with the luminance signal to
obtain the RGB signals. Linear
amplifiers have been chosen for the
RGB inputs so that the circuit is
suitable for incoming signals from the
SCART connector. The contrast and
brightness controls operate on
internal and external signals.
The fast blanking pin has a second
detection level at 3.5 V.
When this level is exceeded the
RGB outputs are blanked so that
“On-Screen-Display” signals can be
applied to the outputs.
The output signal has an amplitude of
approximately 4 V, black-to-white,
with nominal input signals and
nominal control settings. The nominal
black level is 1.3 V.

1. It is possible to start the horizontal oscillator when a current of 5.5 mA is supplied to this pin. In this condition the main
part of the IC is not active and this results in the frequency of the oscillator not being controlled at the correct value.
Consequently, the oscillator frequency will be higher than normal, the maximum deviation will be 75%. When the
start-up function is used the maximum voltage on pin 36 must be limited to 8.8 volts.
2. On set AGC.
3. This parameter is not tested during production and is just given as application information for the designer of the
television receiver.
4. Measured at 10 mV RMS top sync input signal.
5. So called projected zero point, i.e. with switched demodulator.
6. Measured in accordance with the test line given in Fig.11. For the differential phase test the peak white setting is
reduced to 87%.
The differential gain is expressed as a percentage of the difference in peak amplitudes between the largest and
smallest value relative to the subcarrier amplitude at blanking level.
The phase difference is defined as the difference in degrees between the largest and smallest phase angle.
7. This parameter is not tested during production but is guaranteed by the design and qualified by means of matrix
batches which are made in the pilot production period.
8. This figure is valid for the complete video signal amplitude (peak white-to-black), see Fig.12.
9. Insertion (suppression of the interference pulses) to a level of 2.6 V is active only during a strong input signal.
This is because the noise inverter has a negative effect on the sound performance at a weak input signal.
10. The test set-up and input conditions are given in Fig.13. The figures are measured with an input signal of
10 mV RMS.

11. Measured with a source impedance of 75 Ω, where:
(black-to-white)
V
S/N = 20 log
12. To obtain a good noise immunity of the AGC circuit the AGC detector is gated during the sync pulse. This gating is
switched off during the vertical retrace to avoid disturbances of the signal amplitude due to phase errors of the
incoming video signal which are caused by the head-switching of VCRs.
13. When the leakage current of the capacitor exceeds this value it will result in a reduced performance of the AGC
(amplitude variation during line or frame) but it will not result in a hang-up situation.
14. The AFC slope is directly related to the Q-factor of the demodulator tuned circuit. The given AFC steepness is
obtained with a Q-factor of 60. When a lower steepness is required this can be obtained by connecting an external
resistor to the AFC output (the output impedance is 50 kΩ). The AFC off-set is tested with a double sideband input
signal and with the reference tuned circuit tuned to minimum AGC voltage (optimum tuning for the demodulator).
15. For positive modulated signals the FM sound demodulator for the sound is not required. This is because the sound
signal is amplitude modulated. Therefore the TDA8362 can be switched to positive modulation via the de-emphasis
pin (pin 1). When switched to positive modulation the audio switch is set to ‘external’ so that the demodulated audio
signal can be supplied to the input. The option between AM sound and SCART audio signals is achieved by means
of an external switch.
16. The sound IF input is combined with the AF volume control. The IF signal is internally AC coupled to the limiter
amplifier. The volume control voltage must be supplied to this pin via a resistor.

17. V
I
18. VI = 50 mV RMS, f = 4.5/5.5 MHz;
FM: 70 Hz ±50 kHz deviation
AM: 1 kHz at 30% modulation.
20. Audio attenuator at −20 dB; temperature range 10 to 50 °C.
21. In the TDA8361 and TDA8362 the audio and CVBS switches are controlled via the chrominance input pin.
Table 1 lists the various possibilities.
When the DC voltage has a value between 3 and 5 V the switches are set to the S-VHS position. The chrominance
trap is then switched off and separate Y and chrominance signals have to be applied to the inputs (the audio switch
is set to external in this condition). The audio switch is also set to external when the IF amplifier is switched to positive
modulation (see also note 15).
22. Signal with negative-going sync. Amplitude includes sync pulse amplitude.
23. This parameter is measured at nominal settings of the various control voltages.
24. Burst amplitude; for a colour bar with 75% saturation the chrominance signal amplitude is 660 mV (p-p).
25. Nominal contrast is specified as maximum contrast −3 dB. Nominal saturation as maximum −12 dB. The nominal
brightness control voltage is 2.5 V.
26. When the data blanking input pulse exceeds a level of 4 V the RGB outputs are blanked. In this condition it is possible
to supply ‘On-Screen-Display’ signals to the outputs. This blanking overrules both the internal and external
RGB signals.
27. The −3 dB bandwidth of the circuit can be calculated by means of the following equation:
28. The amplitude response curve can be expressed as follows:
A(f) = 1 + K1 − cos (180 x f/3.1 MHz)
and is realised with a transversal peaking filter having delay sections of 160 ns each. In the ‘neutral’ setting K = 0
and in the minimum setting K = −0.5.
The peaking signal amplifier is linear for 250 ns step input signals up to 50 IRE units. For higher amplitudes the
marginal gain is reduced. When the horizontal PLL is not synchronized (no signal present at the video input) the
peaking control voltage is pulled down by means of an internal current. This information can be used to detect
whether an input signal is available.
29. Slicing level independent of sync pulse amplitude.
30. The horizontal and vertical sync are stable while processing Copy Guard signals and signals with phase shifted sync
pulses (stretched tapes). Trick mode conditions of the VCR will also not disturb the synchronization. The value given
is the delay caused by the vertical sync pulse integrator. The integrator has been designed such that the vertical sync
is not disturbed for special anti-copy tapes with vertical sync pulses with an on/off time of 10/22 µs.
31. To obtain a good performance for both weak signal and VCR playback the time constant of the first control loop is
switched depending on the input signal condition. Therefore the circuit contains a noise detector and the time
constant is switched to ‘slow’ when excessive noise is present in the signal (only when the internal video signal is
selected, when the video switch is in the external mode the time constant is always ‘fast’). In the ‘fast’ mode during
the vertical retrace time the phase detector current is increased 50% so that phase errors due to head-switching of
the VCR are corrected as soon as possible.
When no video signal is received the time constant of the first loop is switched to ‘very slow’. This ensures a stable
OSD when the receiver is switched to a channel without transmitter.
The output current of the phase detector for the various conditions is shown in Table 2.
32. Picture shift can be obtained by means of a variable external load on the second phase detector. The control range
is ±2 µs; the required current for this phase shift is ±6 µA.
33. The vertical blanking pulse in the RGB outputs has a width of 22 or 17.5 lines (50 or 60 Hz system). The width of the
vertical sync pulse in the sandcastle pulse is 14 lines. This is to prevent a phase distortion on top of the picture due
to a timing modulation of the incoming flyback pulse.
34. The timing pulses for the vertical ramp generator are obtained from the horizontal oscillator via a divider circuit.
This divider circuit has 2 search modes of operation:
The ‘large window’ mode is switched on when the circuit is not synchronized or, when a non-standard signal is
received (the number of lines per frame in the 50 Hz mode is between 311 and 314 and in the 60 Hz mode between
261 and 264). In the search mode the divider can be triggered between line 244 and line 361 (approximately
45 to 64.5 Hz)
The ‘narrow window’ mode is switched on when more than 15 successive vertical sync pulses are detected in the
narrow window. When the circuit is in the standard mode and a vertical sync pulse is missing the retrace of the
vertical ramp generator is started at the end of the window. Consequently, the disturbance of the picture is very small.
The circuit will switch back to the search window when, for 6 successive vertical periods, no sync pulses are found
within the window.
35. This precorrection is intended to compensate for non-linearity of AC coupled vertical output stages. The value given
indicates the amplitude of the correction waveform with respect to the sawtooth amplitude.
36. At a chrominance input voltage (related to CVBS2) of 660 mV (p-p) (colour bar with 75% saturation i.e. burst signal
amplitude 300 mV (p-p)) the dynamic range of the ACC is +6 and −20 dB.

37. All frequency variations are referenced to 3.58/4.43 MHz carrier frequency.
All oscillator specifications are measured with the Philips crystal series 9922 520.
If the spurious response of the 4.43 MHz crystal is lower than −3 dB with respect to the fundamental frequency for a
damping resistance of 1 kΩ, oscillation at the fundamental frequency is guaranteed.
The spurious response of the 3.58 MHz crystal must be lower than −3 dB with respect to the fundamental frequency
for a damping resistance of 1.5 kΩ.
The catching and detuning range are measured for nominal crystal parameters. These are:
a) load resonance frequency f0 (CL = 20 pF) = 4.433619 or 3.579545 MHz
b) motional capacitance CM = 20.6 fF (4.43 MHz crystal) or (3.58 MHz crystal)
c) parallel capacitance C0 = 5.5 pF (4.43 MHz crystal) or 4.5 pF (3.58 MHz crystal).
The actual load capacitance in the application should be CL = 18 pF to account for parasitic capacitances on
and off chip.
The free-running frequency of the oscillator can be checked by pulling the saturation control pin to the positive supply
rail. In that condition the colour killer is not active so that the frequency off-set is visible on the screen. When two
crystals are connected to the IC the circuit must be forced to one of the crystals during this test to prevent the
oscillator continuously switching between the two frequencies.
38. In the TDA8362 the hue control pin has a double function. When the control voltage has a value of 0 to 5 V (normal
control range) the hue can be controlled when NTSC signals are decoded. When this voltage is increased to a value
greater than 5.5 V the decoder is forced to the PAL standard. When this pin is connected to the positive supply line
via a 10 kΩ resistor the selected CVBS signal, of the CVBS switch, is available. This signal can be applied to the
SECAM decoder TDA8395.
The phase shift of the hue control can be measured at the colour difference outputs (pins 30 and 31).
39. The −(R−Y) and −(B−Y) signals are demodulated with the 90° phase difference of the reference carrier and a gain
ratio −(B−Y)/−(R−Y) = 1.78. The matrixing to the required signals is achieved in the control part.
40. This value indicates the bandwidth of the complete chrominance circuit including the chrominance bandpass filter.
The bandwidth of the demodulator low-pass filter is approximately 1 MHz.
41. The reference signal for the TDA8395 is available only when the crystal oscillator is operating at a frequency of
4.43 MHz. When a SECAM signal is identified this signal is only available during the vertical retrace period thus
avoiding crosstalk with the incoming SECAM signal during scan.
42. When one of the three output signals exceeds this level the gain of the amplifiers is reduced. This is achieved by a
reduction of contrast and thus avoids clipping of the output signals. The discharge current at pin 25 is 0.2 mA. When
the black level exceeds a value of 2 V the maximum peak-to-peak value of the video output signal will be less than
4 V (p-p); this is due to the operation of the peak-white limiter.
43. The signal-to-noise ratio is specified as a peak-to-peak signal with respect to RMS noise (bandwidth 5 MHz). During
the measurement the peaking control voltage is set to nominal.
44. The typical free running frequency is dependent on the crystal which is used for calibration. With 4.4 MHz the typical
free running frequency is 15625, with 3.58 MHz the typical free running frequency is 15734.
Calibration during start-up is always carried out with a 4.4 MHz crystal if no forced mode is used.
