NTE7134
Integrated Circuit
Horizontal and Vertical Deflection Controller
for Monitors
Description:
The NTE7134 is a high performance and efficient solution for autosync monitors in a 32Lead DIP
type package. The concept is fully DC controllable and can be used in applications with a microcon-
troller and standalone in rock bottom solutions.
This device provides synchronization processing, H + V synchronization with full autosync capability,
and very short setting times after mode changes. External power components are givena great deal
of protection. The IC generates the drive waveforms for DCcoupled vertical boosters.
The NTE7134 provides ectended functions e.g. as a flexible SMPS block and an extensive set of ge-
ometry control facilities, providing excellent picture quality.

Note 3. To ensure safe locking of the horizontal oscillator, one of the following procedures is required:
a) Search mode starts always from f
min
. Then the PLL1 filter components are a 3.3nF
capacitor from Pin26 to GND in parallel with an 8.2k
resistor in series with a 47nF
capacitor.
b) Search mode starts either from f
min
or f
max
with HPOS in middle position (I
HPOS
= 60
A).
Then the PLL1 filter components are a 1.5nF capacitor from Pin26 to GND in parallel
with a 27k
resistor in series with a 47nF capacitor.
c) After locking is achieved, HPOS can be operated in the normal way
Note 4. Loading of HPLL1 (Pin26) is not allowed.
Note 5. Oscillator frequency is f
min
when no sync signal is present (no continuous blanking at Pin16).
Note 6. Voltage at HPPL1 (Pin26) is fed to HBUF (Pin27) via a buffer. Disturbances caused by hori-
zontal sync are removed by an internal sampleandhold circuit.

Functional Description:
Horizontal Sync Separator and Polarity Correction
HSYNC (Pin15) is the input for horizontal synchronization signals, which can be DCcoupled TTL sig-
nals (horizontal or composite sync) and ACcoupled negativegoing video sync signals. Video syncs
are clamped to 1.28V and sliced at 1.4V. This results in a fixed absolute slicing level of 120mV related
to sync top.
For DCcoupled TTL signals the input clamping current is limited. The slicing level for TTL signals
is 1.4V.
The separated sync signal (either video or TTL) is integrated on an internal capacitor to detect and
normalize the sync polarity.
Normalized horizontal sync pulses are used as input signals for the vertical sync integrator, the PLL1
phase detector and the frequencylocked loop.
Vertical Sync Integrator
Normalized composite sync signals from HSYNC are integrated on an internal capacitor in order to
extract vertical sync pulses. The integration time is dependent on the horizontal oscillator reference
current at HREF (Pin28). The integrator output directly triggers the vertical oscillator. This signal is
available at VSYNC (normally vertical sync input; Pin14), which is used as an output in this mode.
Vertical Sync Slicer and Polarity Correction
Vertical sync signals (TTL) applied to VSYNC (Pin14) are sliced at 1.4V. The output signal of the sync
slicer is integrated on an internal capacitor to detect and normalize the sync polarity.
If a composite sync signal is detected at HSYNC, VSYNC is used as output for the integrated vertical
sync (e.g. for power saving applications).
Video Clamping/Vertical Blanking Generator
The video clamping/vertical blanking signal at CLBL (Pin16) is a twolevel sandcastle pulse which
is especially suitable for video ICs, but also for direct applications in video output stages.
The upper level is the video clamping pulse, which is triggered by the trailing edge of the horizontal
sync pulse. The width of the video clamping pulse is determined by an internal monoflop.
CLSEL (Pin10) is the selection input for the position of the video clamping pulse. If CLSEL is con-
nected to GND, the clamping pulse is triggered with the trailing edge of horizontal sync. For a clamping
pulse which starts with the leading edge of horizontal sync, Pin10 must be connected to V
CC
.
The lower level of the sandcastle pulse is the vertical blanking pulse, which is derived directly from
the internal oscillator waveform. It is started by the vertical sync and stopped with the start of the verti-
cal scan. This results in optimum vertical blanking.
Blanking will be activated continuously, if one of the following conditions is true:
No horizontal flyback pulses at HFLB (Pin1)
Xray protection is activated
Soft start of horizontal drive (voltage at HPPL2 (Pin31) is low)
Supply voltage at V
CC
(Pin9) is low
PLL1 is unlocked while frequencylocked loop is in search mode
Blanking will not be activated if the horizontal sync frequency is below the valid range or there are no
sync pulses available.
background image
Functional Description (Cont'd):
FrequencyLocked Loop
The frequencylocked loop can lock the horizontal oscillator over a wide frequency range. This is
achieved by a combined search and PLL operation. The frequency range is preset by two external
resistors and the recommended ratio is
f
min
f
max
=
1
3.5
Larger ranges are possible by extended applications.
Without a horizontal sync signal the oscillator will be freerunning at f
min
. Any change of sync condi-
tions is detected by the internal coincidence detector. A deviation of more than 4% between horizontal
sync and oscillator frequency switches the horizontal section into search mode. This means that PLL1
control currents are switched off immediately. Then the internal frequency detector starts tuning the
oscillator. Very small DC currents at HPLL1 (Pin26) are used to perform this tuning with a well defined
change rate. When coincidence between horizontal sync and oscillator frequency is detected, the
search mode is replaced by a normal PLL operation. This operation ensures a smooth tuning and
avoids fast changes of horizontal frequency during catching.
In this concept it is not allowed to load HPLL1. The frequency dependent voltage at this pin is fed inter-
nally to HBUF (Pin27) via a sampleandhold and buffer stage. The sampleandhold stage re-
moves all disturbances caused by horizontal sync or composite vertical sync from the buffered volt-
age. An external resistor from HBUF to HREF defines the frequency range.
See also hints for locking procedure in Note 2 of the "Electrical Characteristics" section of this data
sheet.
P
LL1
Phase Detector
The phase detector is a standard type using switched current sources. The middle of the horizontal
sync is compared with a fixed point of the oscillator sawtooth voltage. The PLL1 loop filter is connected
to HPLL (Pin26).
Horizontal Oscillator
This oscillator is a relaxation type and requires a fixed capacitor of 10nF at HCAP (Pin29). For opti-
mum jitter performance the value of 10nF must not be changed.
The maximum oscillator frequency is determined by a resistor from HREF to GND. A resistor from
HREF to HBUF defines the frequency range.
The reference current at HREF also defines the integration time constant of the vertical sync integration.
Calculation of Line Frequency Range
First the oscillator frequencies f
min
and f
max
have to be calculated. This is achieved by adding the
spread of the relevant components to the highest and lowest sync frequencies f
S(min)
and f
S(max)
. The
oscillator is driven by the difference of the currents in R
HREF
and R
HBUF
. At the highest oscillator fre-
quency R
HBUF
does not contribute to the spread. The spread will increase towards lower frequencies
due to the contribution of R
HBUF
. It is also dependent on the ratio

P
LL2
Phase Detector
The PLL2 phase detector is similiar to the PLL1 detecrtor and compares the line flyback pulse at HFLB
(Pin1) with the oscillator sawtooth voltage. The PLL2 detector thus compensates for the delay in the
external horizontal deflection circuit by adjusting the phase of the HDRV (Pin7) output pulse.
The phase between horizontal flyback and horizontal sync can be controlled at HPOS (Pin30).
If HPLL2 is pulled to GND, horizontal output pulses, vertical output currents and B+ control pulses
are inhibited. This means, HDRV (Pin7), BDRV (Pin6) VOUT1 (Pin13) and VOUT2 (Pin12) are float-
ing in this state. PLL2 and the frequencylocked loop are disabled, and CLCB (Pin16) provides a con-
tinuous blanking signal.
This option can be used for soft start, protection and powerdown modes. When the HPLL2 voltage
is released again, an automatic soft start sequence will be performed.
The soft start timing is determined by the filter capacitor at HPLL2 (Pin31), which is charged with a
constant current during soft start. In the beginning the horizontal driver stage generates very small
output pulses. The width of thses pulses increases with the voltage at HPLL2 until the final duty factor
is reached. At this point BDRV (Pin6), VOUT1 (Pin13 and VOUT2 (Pin12) are reenabled. The volt-
age at HPLL2 continues to rise until PLL2 enters its normal operating range. The internal charge cur-
rent is now disabled. Finally PLL2 and the frequencylocked loop are enabled, and the continuous
blanking at CLBL is removed.
Horizontal Phase Adjustment
HPOS (Pin30) provides a linear adjustment of the relative phase between the horizontal sync and
oscillator sawtooth. Once adjusted, the relative pahse remains constant over the whole frequency
range.
Application hint: HPOS is a current input, which provides an internal reference voltage while I
HPOS
is in the specified adjustment current range, By grounding HPOS the symmetrical control range is
forced to its center value, therefore the pahse between horizontal sync and horizontal drive pulse is
only determined by PLL2.
Output Stage for Line Drive Pulses
An open collector output stage allows direct drive of an inverting driver transistor because of a low
saturation voltage of 0.3V at 20mA. To protect the line deflection transistor, the output stage is dis-
abled (floating) for low supply voltage at V
CC
.
The duty factor of line drive pulses is slightly dependent on the actual line frequency. This ensures
optimum drive conditions over the whole frequency range.

Functional Description (Cont'd):
XRay Protection
The Xray protection input XRAY (Pin2) provides a voltage detector with a precise threshold. If the
input voltage at XRAY exceeds this threshold for a certain time, an internal latch switches the IC into
protection mode. In this mode several pins are forced into defined states:
Horizontal output stage (HDRV) is floating
B+ control driver stage (BDRV) is floating
Vertical output stages (VOUT1 and VOUT2) are floating
CLBL provides a continuous blanking signal
The capacitor connected to HPLL2 (Pin31) is discharged
To reset the latch and return to normal operation, V
CC
has to be temporaily switched off.
Vertical Oscillator and Amplitude Control
This stage is designed for fast stabilization of vertical amplitude after changes in sync frequency con-
ditions. The freerunning frequency f
osc(V)
is determined by the resistor R
VREF
connected to Pin23
and the capacitor C
VCAP
connected to Pin24. The value of R
VREF
is not only optimized for noise and
linearity performance in the whole vertical and EW section, but also influences several internal refer-
ences, Therefore the value of R
VREF
must not be changed. capacitor C
VCAP
should be used to select
the freerunning frequency of the vertical oscillator in accordance with the following formula:
fosc(V) =
1
10.8 x R
VREF
x C
VCAP
To achieve a stabilized amplitude the freerunning frequency f
osc(V)
, without adjustment, should be
at least 10% lower than the minimum trigger frequency. The contributions shown in Table 2 can be
assumed.

Application hint: VAGC (Pin22) has a high input impedance during scan, thus the pin must not be
loaded externally. Otherwise nonlinearities in the vertical output currents may occur due to the
changing charge current during scan.
Application hint: The full vertical sync range of 1 : 2.5 can be made usable by incorporating an ad-
justment of the freerunning frequency. Also the complete sync range can be shifted to higher fre-
quencies (e.g. 70 to 160Hz) by reducing the value of C
VCAP
.
Adjustment of Vertical Size, Vertical Shift and SCorrection
VPOS (Pin17) is the input for the DC adjustable vertical picture shift. This pin provides a phase shift
at the sawttoth output VOUT1 and VOUT2 (Pin13 and Pin12) and the EW drive output EWDRV
(Pin11) in such a way that the whole picture moves vertically while maintaining the correct geometry.
The amplitude of the differential output currents at VOUT1 and VOUT2 can be adjusted via input
VAMP (Pin18). This can be a combination of a DC adjustment and a dynamic waveform modulation.
VSCOR (pin19) is used to adjust the amount of vertical Scorrection in the output signal.
background image
Functional Description (Cont'd):
Adjustment of Vertical Size, Vertical Shift and SCorrection (Cont'd)
The adjustments for vertical size and vertical shift also affect the wavweforms of the EW parabola and
the vertical Scorrection. The result of this interaction is that no readjustment of these parameters
is necessary after an adjustment of vertical picture size or position.
Application hint: VPOS is a current input which provides an internal reference voltage while I
VPOS
is in the specified adjustment current range. By grounding VPOS (Pin17) the symmetrical control
range is forced to its center value.
Application hint: VSCOR is a current input at 5V. Superimposed on this level is a very small posi-
tivegoing vertical sawtooth, intended to modulate an external longtailed transistor pair. This en-
ables further optional DC controls of functions which are not directly accessible such as vertical tilt
or vertical linearity.
EW Parabola (Including Horizontal Size and Trapezium Correction)
EWDRV (Pin11) provides a complete EW drive waveform. EW parabola amplitude, DC shift (horizon-
tal size) and trapezium correction can be controlled via separate DC inputs.
EWPAR (Pin21) is used to adjust the parabola amplitude. This can be a combination of a DC adjust-
ment and a dynamic waveform modulation.
The EW parabola amplitude also tracks with vertical picture size. The parabola waveform itself tracks
with the adjustment for vertical picture shift (VPOS).
EWWID (Pin32) offers two modes of operation:
Mode 1
Horizontal size is DC controlled via EWWID (Pin32) and causes a DC shift at the EWDRV
output. Also the complete waveform is multiplied internally by a signal proportional to the
line frequency (which is detected via the current at HREF (Pin28). This mode is to be used
for driving EW modulator stages which require a voltage proportional to the line frequency.
Mode 2
EWWID (Pin32) is grounded. Then EWDRV is no longer multiplied by the line frequency.
The DC adjustment for horizontal size must be added to the input of the B+ control amplifier
BIN (Pin5). This mode is to be used for driving EW modulations which require a voltage
independent of the line frequency.
EWTRP (Pin20 is used to adjust the amount of trapezium correction in the EW drive waveform.
Application hint: EWTRP (Pin20) is a current input at 5V. Superimposed on this level is a very small
vertical parabola with positive tips, intended to modulate an external longtailed transistor pair. This
enables further optional DC controls of functions which are not directly accessible such as EWcor-
ner, vertical focus or EW pin balance.
Application hint: By grounding EWTRP (Pin20) the symmetrical control range is forced to its center
value.
B+ Control Function Block
The B+ control function block of the EASDC consists of an Operatgional Transcondutance Amplifier
(OTA), a voltage comparator, a flipflop and a discharge circuit. This configuration allows easy ap-
plications for different B+ control concepts.
General Description
The noninverting input of the OTA is connected internally to a high precision reference voltage. The
inverting input is connected to BIN (Pin5). An internal clamping circuit limits the maximum positive
output voltage of the OTA. The output itself is connected to BOP (Pin3) and to the inverting inpuyt of
the voltage comparator. The noninverting input of the voltage comparator can be accessed via
BSENS (Pin4).
background image
Functional Description (Cont'd):
B+ Control Function Block (Cont'd)
B+ drive pulses are generated by an internal flipflop and fed to BDRV (Pin6) vai an open collector
output stage. This flipflop will be set at the rising edge of the signal at HDRV (Pin7). The falling edge
of the output signal at BDRV has a defined delay of t
d(BDRV)
to the rising edge of the HDRV pulse.
When the voltage at BSENS exceeds the voltage at BOP, the voltage comparator output resets the
flipflop and therefore, the open collector stage at BDRV is floating again.
An internal discharge circuit allows a well defined discharge of capacitors at BSENS. BDRV is active
at a low level output voltage thus, it requires an external inverting driver stage.
The B+ function block can be used for B+ deflection modulators in either of two modes:
D
Feedback Mode
In this application the OTA is used as an error amplifier with a limited output voltage range. The
flipflop will be set at the rising edge of the signal at HDRV. A reset will be generated when the
voltage at BSENS taken from the current sense resistor exceeds the voltage at BOP.
If not reset is generated within a line period, the rising edge of the next HDRV pulse forces the
flipflop to reset. The flipflop is set immediately after the voltage at BSENS has been dropped
below the threshold voltage V
RESTART(BSENS)
.
D
Feed Forward Mode
This application uses an external RC combination at BSENS to provide a pulse width which is inde-
pendent from the horizontal frequency. The capacitor is charged via an external resistor and dis-
charged by the internal discharge circuit. For normal operation the discharge circuit is activated
when the flipflop is reset by the internal voltage comparator. Now the capacitor will be discharged
with a constant current until the internally controlled stop level V
STOP(BSENS)
is reached. This level
will be maintained until the rising edge of the next HDRV pulse sets the flipflop again and disables
the discharge circuit.
If no reset is generated within a line period, the rising edge of the next HDRV pulse automatically
starts the discharge sequence and resets the flipflop. When the voltage at BSENS reaches the
threshold voltage V
RESTART(BSENS)
, the discharge circuit will be disabled automatically and the
flipflop will be set immediately. This behaviour allows a definition of the maximum duty cycle of
the B+ control drive pulse by the relationship of charge current to discharge current.
Supply Voltage Stabilizer, Reference and Protection
The ASDC provides an internal supply voltage stabilizer for excellent stabilization of all internal refer-
ences. An internal gap reference especially designed for lownoise is the reference for the internal
horizontal and vertical supply voltages. All internal reference currents and drive current for the vertical
output stage are derived from this voltage via external resistors.
A special protection mode has been implemented in order to protect the deflection stages and the
picture tube during startup, shutdown and fault conditions. This protection mode can be activated
as shown in Table 3.

Supply Voltage Stabilizer, Reference and Protection (Cont'd)
When protection mode is active, several pins of the ASDC are forced into a defined state:
HDRV (Horizontal Driver Output) is floating
BDRV (B+ Control Driver Output) is floating
VOUT1 and VOUT2 (Vertical Outputs) are floating
CLBL provides a continuous blanking signal
The capacitor at HPLL2 is discharged
If the protection mode is activated via the supply voltage at Pin9, all thesae actions will be performed
in a well defined sequence. For activation via Xray protection or HPLL2 all actions will occur simulta-
neously.
The return to normal operation is performed in accordance with the startup sequence, if the reset
was caused by the supply voltage at Pin9. The first action with increasing supply voltage is the activa-
tion of continuous blanking at CLBL. When the threshold for activation of HDRV is passed, an internal
current begins to sharge the external capacitor at HPLL2 and PLL2 soft start sequence is performed.
In the beginning of this phase the horizontal driver stage generates very small output pulses. The
width of these pulses increases with the voltage at HPLL2 until the final duty cycle is reached. Then
the PLL2 voltage passes the threshold for activation of BDRV, VOUT1 and VOUT2.
For activation of these pins not only the PLL2 voltage, but also the supply voltage, must have passed
the appropriate threshold. A last pair of thresholds has to be passed by PLL2 voltage and supply volt-
age before the continuous blanking is finally removed, and the operation of PLL2 and frequency
locked loop is enabled.
A return to the normal operation by releasing the voltage at HPLL2 will lead to a slightly different se-
quence. Here the activation of all functions is influenced only by the voltage at HPPL2.
Application hint: Internal discharge of the capacitor at HPLL2 will only be performed, if the protec-
tion mode was activated via the supply voltage or Xray protection.
