Precautions

Follow these safety and servicing precautions to prevent damage and to protect against potential hazards such as electrical shock and X-rays.

1.1 Safety Precautions

1-1-1 Warnings

1. For safety purpose, do not attempt to modify the circuit board, and always disconnect the AC power before performing servicing on the monitor.

2. Operation of the monitor outside its cabinet or with the cover removed involves the risk of shock hazard. Repair work on the monitor should only be attempted by service personnel who are thoroughly familiar with all necessary safety precautions and procedures for working on high voltage equipment.

3. Do not lift the CRT by the neck. After completely discharging the high voltage anode, handle the CRT only when wearing shatterproof goggles. Try to keep the CRT away from the body during handling.

4. High voltage should always be kept at the rated value, no higher. Only when high voltage is excessive are X-rays capable of penetrating the shell of the CRT. Operation at high voltages may also cause failure of the CRT or high voltage circuitry.

5. The CRT is especially constructed to limit X-ray emission to 0.5mR/HR at 300 microamperes anode current. To ensure continued X-ray protection, replace the CRT with only the same or equivalent type as the original, and adjust the anode’s voltage to the designated maximum rating, never to exceed.

1-1-2 Safety Checks

Before returning the monitor to the user, perform the following safety checks:

1. Inspect to make certain that each lead dress is not pinched or that hardware is not lodged between the chassis and other metal parts in the monitor.

2. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc.

3. AC Leakage Current Check Always perform the AC Leakage Current Check on the exposed metal parts, including metal cabinets, screwheads and control shafts, as follows: a) Plug the AC line cord directly into a rated AC outlet. Do not use an isolation transformer during the

check.

b) Use an AC voltmeter with at least 5000 ohms per volt sensitivity as follows:

Connect a 1500 ohms, 10 watt resistor paralleled by a 0.15uF AC capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduct or electrical ground connected to earth ground, as shown in the Figure 1-1. Measure the AC voltage across the combination of resistor and capacitor.

Cabinet part

To known

Earth ground

Figure 1-1. Set Up For AC Leakage Current Check

c) Reverse the AC plug at the AC outlet and repeat the steps for AC voltage measurements for each

exposed metal part.

d) Voltage reading must not exceed 0.3 volts RMS, equivalent to 0.2 milliampere AC. Any value ex-

ceeding this limits ill constitute a potential shock hazard and must be corrected immediately

1-1-1 Product Safety Notices

Many electrical and mechanical parts in this chassis have special safety-related characteristics which are often not evident from visual inspection. The protection afforded by them may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Before replacing any of these components, consult the Recommended Spare Parts List given at the end of this manual. Any of the replacements that do not provide the same safety characteristics may result in shock, fire, X-ray emission or other hazards.

1.2 Servicing Precautions

Warning: An electrolytic capacitor installed with the wrong polarity might explode.

Caution: Before performing servicing covered by this service manual, read and follow the Safety Precau-

tions section of this manual.

Note: If unforeseen conflict between the following servicing precautions and of the safety precautions,

always follow the safety precautions

1. Follow closely the servicing precautions printed on the monitor cabinet and chassis.

2. Always unplug the AC power cord from the AC power source before removing or installing any component or assembly, disconnection PCB plugs or connectors and connecting a test component in parallel with a capacitor.

3. When replacing parts or circuit boards, clamp the lead wires around the unit before soldering.

4. When replacing a high wattage resistor (>0.5W metal oxide film resistor) in the circuit board, keep the resistor about 1 cm (1/2 inch) away from the circuit board.

5. Keep wires away from the high voltage or high temperature components.

6. Keep wires in their original positions so as to minimize interference.

7. Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last.

1. Power supply circuit

 Outline

This power supply unit adopts the switching mode technology, and is an off-line mode type unit that provided several different DC outputs. The scanning frequency is available in different values ranging from 31 kHz to 69 kHz. Moreover, it is capable to operate at an AC input voltage of 100V ~ 240V and an

AC frequency of 50-60 Hz±3Hz. The block diagram is the functional construction schematics, that shows the major functions of this power supply unit.

 Harmonics (OPTION)

L107 is a harmonic choke circuit that reduces the harmonic peak currents, for the purpose of fulfilling the requirement items of IEC 1000-3-2.

 EMI

The EMI circuit has a 2-stage construction, with the first stage consisting of the common mode choke unit and one X-capacitor, and the second stage consisting of the common mode choke unit and four Ycapacitors. R101 is the bleed resistor of the X-capacitor. When the power supply switch is turned OFF, this resistor carries out the emergency charging of the capacitor C101. The EMI is the circuit that prevents the monitor switching noise from being generated, there by minimizing the negative influence on the other electronic equipment.

 AC rectifier and smoothing capacitor

The AC input is rectified by means of the full-bridge rectifier, that consists of the diodes D101 to D104. The AC voltage is converted into the DC voltage by passing through the next stage, that consists of the smoothing capacitor C105. TH101 is a NTC thermistor for the power supply at the in-rush current limit.

 Degaussing circuit

The degaussing circuit consists of the PTC thermistor TH102, the degaussing coil and the relay RL101. The relay is controlled by means of the +12V control signal coming from the CPU.

 Transformer and energy induction

1) When the PWM controls IC KA3842A chip, a driving pulse is generated at the gate of the transistor Q101, and Q101 turns ON. The current returns from the “plus” (+) side of the energy-supplying capacitor C105 to the “minus” (-) side of the same capacitor C105, passing through the transformer Q101 D-S. During the ON cycle, the energy is stored in the transformer T101. The transistor Q101 turns OFF when the driving pulse disappears from Q101. As a result, all voltages of the dot ends of the winding flow to the positive direction and reach the fly-back rectifier. At that point of time, the diodes of the rectifier of the secondary side turn ON, a temporary energy is induced at the secondary side, and the ON cycle of the driving pulse is repeated.

38

2) The power supply MOS FET Q101 carries out the ON/OFF operation of the control unit, by means of U101 KA3842A. KA3842A is a PWM (pulse width modulation) IC chip, with 16 V starting voltage and 10 V cut-off voltage. The following list shows the pin layout of KA3842A pulse width modulation IC chip.

Pin 1: Feedback Pin 2: Compensation Pin 3: Current sensor Pin 4: Oscillator Pin 5: Ground (GND) Pin 6: Pulse output Pin 7: VCC Pin 8: VREF (5.1 V)

3) Overcurrent protection R1 11 is a sensor resistor, and it has the function of increasing the current of this loop when the output of the secondary side is either in the overloaded state or is insufficient. Since the current passing through the R1 11 sensor resistor has voltage dropping effect, the operation of the output pulse is stopped when a voltage lower than 1 Volt is detected at the pin number 3 of the KA3842A 3chip, and the switch of the power supply MOS FET is kept in the “break” state until the VCC voltage is charged up to 16 Volts, and the operation of U101 KA3842A is resumed. When it is not clearly known whether there is voltage shortage or not, however, this circuit repeats the ON/OFF switching, and the power supply LED lights up.

4) Starting circuit The resistor R122 and R123 and the transistor U103 and diode D131 and resistor R169 and zener diode ZD101 are for the starting operation. When the circuit starts its operation, the power supply transformer T101 supplies the auxiliary 12 Volt power to the control IC chip U101 via pins 6 and 7 of the winding transformer T101.

5) Synchronization circuit The synchronization signal is induced from the fly-back transformer (FBT), and carries out the synchronization with the power supply frequency. The frequency range is from 31 kHz to 70 kHz, and the component elements of the synchronization circuit are C114, R116, D109, R115 and R117.

6) Feedback circuit The feedback circuit loop induces the 12 V voltage through the pin 6 and the pin 7 of the power supply transformer. That voltage is connected with the pin 3 of the IC chip U101 by passing through U103, R122, R123 and passing next through R10A, VR101 and R151. This is a regular loop.

7) Snubber circuit The snubber circuit has the function of clamping the ON/OFF spikes of the power supply MOS-FET, and its component elements D105, C106, R106 make up a snubber that turns OFF the power supply MOS-FET.

8) Secondary rectifier and smoothing rectifier The secondary rectifier is a harmonic rectifier consisting of D111, C124 and R128, and it works as a snubber circuit as well. The capacitors C120 and C138 are the smoothing rectifier working on the 49 Volt DC output. There are also other DC outputs, such as 80 Volt (D110), 13.5 Volt (D112) and 6.3 V olt (D1 13).

 Power saving

Suspend mode : Every DC voltage operation of the CRT is turned OFF.

The color of the power LED101 switches from green to orange.

OFF mode : This is the mode in which the CPU control unit turns OFF the power supply, but

the power turns ON when the user touches the keyboard. The power LED switches to dark orange color.

1) When the power switch is turned ON when there is nothing being entered in the video cable. At that time, if the video is shifted from the free-run mode to the suspend mode, the transistor Q107 turns OFF and the operation returns to the OFF mode within a few seconds.

2)As for the sequence of steps that turn the operation to the OFF mode, if the keyboard is not touched for a given period of time that a preset in advance, the CPU outputs the LOW level signal to the transistor Q107, then Q105 turns OFF, the transistor Q108 and Q104 turns OFF. As a result the power is shut out at that state.

3) When the user touches the keyboard in the OFF mode, the operation is resumed, the video signals V-SYNC and H-SYNC turn ON the CPU via resistor R129 and R159, then the transistor Q105 and Q107 turn ON, the transistors Q104 and Q108 turn ON. As a result the operation returns to the ON state.

 DC/DC

The DC/DC voltage is DC 49 volts, and since the set-up voltage is variable from 62 volts to 160 volts,

it is variable depending on the horizontal synchronism. The frequency band is variable from 31 kHz to 69 kHz. The voltage is fed back from the fly-back transformer (FBT). The DC/DC output voltage is used as high-voltage input of FBT T301.

1) DC/DC is a step-up circuit, and consists mainly of the choke L304, the transistor Q319, the diode D335 and U302.

2) When the PWM controls U302 IC TDA4857, a driving pulse is generated at the gate of the transistor Q319, and the transistor Q319 turns ON. During the ON cycle, the energy is stored in the choke L304. The transistor Q319 turns OFF when the driving pulse disappears from the gate of the transistor Q319. As a result, the voltage at the dot terminal of the winding flows in the positive direction and goes to the fly-back rectifier. The energy stored in the choke L304 is entered in the FBT, passing through the choke L304, the diode D335 and the capacitor C307.

3) The feedback is detected by the FBT via diode D310, the capacitor C326, the resistor R349 the variable resistor VR302 and the fixed resistor R382, and is connected to the U302 pin 5. This is loop is the regular type one.

4) The frequency of the synchronization signal coming from video H-SYNC is variable from 31 kHz to 69 kHz. The circuit consists of the R30X.

5) The soft start circuit consists of the resistor R30P, the capacitor C309, the diode D303 and the Q326.

I/O Port

I/O Port A

Pin PA0 and PA1 are shared with DDC interface SDA1 and SCL1 When ENDDC bit is “0”, These two pins becomes I/O port. If PA0OE bit is set, Pin PA0 is an open-drain output. If PA0OE is cleared, Pin PA0 is an input pin with no internal pull-up resistor. The operation of PA1 is same as PA0. Fig. 2 Shows the structure of PA0.

Pin PA2 to PA6 are shared with PWM output. When corresponding EPWMx bit is “0”, the pin is I/O port. If PAxOE bit is set, it is a push-pull type output. If PAxOE bit is cleared, it is an input pin with internal pullup resistor. Pin PA7 is shared with PWM13 output and clamp pulse output. When both EPWM13 bit and ENCLP bit are “0”, this pin becomes I/O port. If PA7OE bit is set, it is a push-pull type output. If PA7OE bit is cleared, it is an input pin with internal pull-up resistor.

SYNC Processor

The functional block diagram of SYNC Processor is shown in Fig. 4. It contains H and V polarity detection circuit, H and V frequency counter, composite sync signal separation circuit, free-running H and V sync signal generator, vedio signal generation circuit for burn-in test and clamp pulse generator.

Horizontal Polarity Detect

The horizontal polarity is detected by sampling HIN signal at 5.5~6.5us after rising and falling edge of HIN. If the result of sampling is low and lasts 192~256us with no change, the polarity is positive (HINPOL=1). If the result of sampling is high and lasts 192~256us with no change, the polarity is negative (HINPOL=0).

Vertical Polarity Detect

Vertical polarity is detected by sampling VIN level at 2.048ms after rising edge of VIN. If the level is low, the polarity is positive (VINPOL=1). If the level is high, the polarity is negative (VINPOL=0). But if SEPART bit is set, the VINPOL bit is “1” because the Vsync from composite signal separator is always positive polarity.

Output Polarity Control

The polarities of HOUT and VOUT are controlled by HOPOL and VOPOL bites. When the bit is set, the output polarity is positive. When the bit is cleared, the output polarity is negative.

Composite Sync Signal Separator

Composite sync signal separator extract Vsync signal from HIN or SOGIN input pin by filtering pulses which is less than 6us. The output Vsync signal will be widened about 5.5~6.5us. The output Hsync will be replaced by 2us pulse during Vsync pulse.

The composite sync signal separator can handle H+V and H exclusive OR V signals. Fig. 5 shows the timig relationship of the extracted H and V sync signals.

If Hsync output do not want to insert pseudo H pulses (EXTRHS signal) during Vsync pulse, set BYPASS bit can let HOUT pin output waveform same as Hsync input (Note: polarity can be controlled by HOPOL bit).

Free-running sync signal and self-test pattern The self-generated free run sync signals are output from HOUT and VOUT pins when ENFREE bit is set. Four kinds of standard VESA timings are selected by FREE1 and FREE0 bits. Self-test pattern signal is output form PAT pin when ENPAT bit is set. PAT1 and PAT0 bits select different self-test pattern.

FUNCTIONAL DESCRIPTION

Horizontal sync separator and polarity correction

HSYNC (pin 15) is the input for horizontal synchronization signals, which can be DC-coupled TTL signals (horizontal or composite sync) and AC-coupled negative-going video sync signal. Video syncs are clamped to 1.28V and sliced at 1.4V. This results in a fixed absolute slicing level of 120 mV related to top sync.

For DC-coupled TTL signals the input clamping current is limited. The slicing level for TTL signals is 1.4 V.

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 frequency-locked 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 (pin 28). The integrator output directly triggers the vertical oscillator.

Vertical sync slicer and polarity correction

Vertical sync signals (TTL) applied to VSYNC (pin 14) 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. The output signals of vertical sync integrator and sync normalizer are disjuncted before they are fed to the vertical oscillator.

Video clamping/vertical blanking generator

The video clamping/vertical blanking signal at CLBL (pin

16) is a two-level sandcastle pulse which is especially suit-

able for video ICs such as the TDA488x family, but also for direct applications in video output stages.

The upper level is the video clamping pulse, which is triggered by the horizontal sync pulse. Either the leading or trailing edge can be selected by setting control bit CLAMP via the I²C-bus. The width of the video clamping pulse is determined by an internal single-shot multivibrator.

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 vertical scan. This results in optimum vertical blanking. Two different vertical blanking times are accessible, by control bit VBLK, via the I²C-bus.

Blanking will be activated continuously if one of the following conditions is true:

Soft start of horizontal and B+ drive [voltage at HPLL2 (pin 30) pulled down externally or by the I²C-bus] PLL1 is unlocked while frequency-locked loop is in search mode No horizontal flyback pulses at HFLB (pin 1) X-ray protection is activated Supply voltage at Vcc (pin 10) is low

Horizontal unlock blanking can be switched off, by control bit BLKDIS, via the I²C-bus while vertical blanking is maintained.

Frequency-locked loop

The frequency-locked 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 maximum ratio is

1

6.5

f

max

=

This can, for instance, be a range from 15.625 to 90kHz with all tolerance included.

Without a horizontal sync signal the oscillator will be freerunning at f

min

. Any change of sync conditions 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. The internal frequency detector then starts tuning the oscillator. Very small DC currents at HPLL1 (pin

26) 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 first replaced by a soft-lock mode which lasts for the first part of the next vertical period. The soft-lock mode is then replaced by a normal PLL operation. This operation ensures 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 internally to HBUF (pin 27) via a sample-and-hold and buffer stange. The sample-and-hold stage removes all disturbances caused by horizontal sync or composite vertical sync from the buffered voltage. An external resistor connected between pins HBUF and HREF defines the frequency range.

Out-of-lock indication (pin HUNLOCK)

Pin HUNLOCK is floating during search mode, or if a protection condition is true. All this can be detected by the microcontroller if a pull-up resistor is connected to its own supply voltage.

For an additional fast vertical blanking at grid 1 of the picture tube a 1 V signal referenced to ground is available at this output. The continuous protection blanking (see Section “Video clamping/vertical blanking generator”) is also available at this pin. Horizontal unlock blanking can be switched off, by control bit BLKDIS via the I²C-bus while vertical blanking is maintained.

I²C-bus autosync deflection controller for PC monitors TDA4857

Horizontal oscillator

The horizontal oscillator is of the relaxation type and requires a capacitor of 10 nF at HCAP (pin 29). For optimum jitter performance the value of 10 nF must not be changed.

The minimum oscillator frequency is determined by a resistor from HREF to ground. A resistor connected between pins HREF and HBUF defines the frequency range.

The reference current at pin HREF also defines the integration time constant of the vertical sync integration.

Calculation of line frequency range

The oscillator frequencies fmin and fmax must first be calculated. This is achieved by adding the spread of the relevant components to the highest and lowest sync frequencies f

sync(min)

and f

sync(max)

. The oscillator is driven by the

currents in R

and R

HBUF.

PLL1 phase detector

The phase detector is a standard type using switched current sources, which are independent of horizontal frequency. It compares the middle of horizontal sync with a fixed point on the oscillator sawtooth voltage. The PLL1 loop filter is connected to HPLL1 (pin 26).

See also Section “Horizontal position adjustment and corrections”.

Horizontal position adjustment and corrections

Alinear adjustment of the relative phase between the horizontal sync and the oscillator sawtooth (in PLL1 loop) is achieved via register HPOS. Once adjusted, the relative phase remains constant over the whole frequency range.

Correction of pin unbalance and parallelogram is achieved by modulating the phase between oscillator sawtooth and horizontal flyback (in loop PLL2) via registers HPARAL and HPINBAL. If those asymmetric EW corrections are performed in the deflection stage, both registers can be disconnected from the horizontal phase via control bit ACD. This does not change the output at pin ASCOR.

Horizontal moire cancellation

To achieve a cancellation of horizontal moire (also known as ‘video moire’), the horizontal frequency is divided-bytwo to achieve a modulation of the horizontal phase via PLL2. The amplitude is controlled by register HMOIRE. To avoid a visible structure on screen the polarity changes with half of the vertical frequency. Control bit MOD disables the moire cancellation function.

PLL2 phase detector

The PLL2 phase detector is similar to the PLL1 detector and compares the line flyback pulse at HFLB (pin 1) with the oscillator sawtooth voltage. The control currents are independent of the horizontal frequency. The PLL2 detector thus compensates for the delay in the external horizontal deflection circuit by adjusting the phase of the HDRV (pin 8) output pulse.

An external modulation of the PLL2 phase is not allowed, because this would disturb the pre-correction of the horizontal focus parabola.

Soft start and standby

If HPLL2 is pulled to ground, either by an external DC current or by resetting register SOFTST, the horizontal output pulses and B+ control driver pulses will be inhibited. This means that HDRV (pin 8) and BDRV (pin 6) are floating in this state. In both cases PLL2 and the frequency-lock loop are disabled, and CLBL (pin 16) provides a continuous blanking signal and HUNLOCK (pin 17) is floating.

This option can be used for soft start, protection and powerdown modes. When pin HPLL2 is released again, an automatic soft start sequence on the horizontal drive as well as on the B-drive output will be performed.

A soft start can only be performed if the supply voltage for the IC is a minimum of 8.6V.

The soft start timing is determined by the filter capacitor at HPLL2 (pin 30), 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 these pulses increases with the voltage at HPLL2 until the final duty cycle is reached. The voltage at HPLL2 increases further and performs a soft start at BDRV (pin 6) as well. After BDRV has reached full duty cycle, the voltage at HPLL2 continues to rise until HPLL2 enters its normal operating range. The internal charge current is now disabled. Finally PLL2 and the frequency-locked loop are activated. If both functions reach normal operation, HUNLOCK (pin 17) switches from the floating status to normal vertical blanking, and continuous blanking at CLBL (pin 16) is removed.

Output stage for line drive pulses [HDRV (pin 8)]

An open-collector output stage allows direct drive of an inverting driver transistor because of a low saturation voltage of 0.3V at 20mA. T o protect the line deflection transistor, the output stage is disabled (floating) for a low supply voltage at Vcc.

The duty cycle of line drive pulses is slightly dependent on the actual horizontal frequency. This ensures optimum drive conditions over the whole frequency range.

X-ray protection

The X-ray protection input XRAY (pin 2) provides a voltage detector with a precise threshold. If the input voltage at XRAY exceeds this threshold for a certain time, then control bit SOFTST is reset, which switches the IC into protection mode. In this mode several pins are forced into defined states:

HUNLOCK (pin 17) is floating The capacitor connected to HPLL2 (pin 30) is discharged Horizontal output stage (HDRV) is floating B+ control driver stage (BDRV) is floating CLBL provides a continuous blanking signal.

There are two different methods of restarting ways the IC:

1. XSEL (pin 9) is opeb-circuit or connected to ground. The

control bit SOFTST must be set to logic 1 via the I²Cbus. Then the IC returns to normal operation via soft start.

2. XSEL (pin 9) is connected to Vcc via an external resistor.

The supply voltage of the IC must be switched off for a certain period of time, before the IC can be restarted again using the standard power-on procedure.

Vertical oscillator and amplitude control

This stage is designed for fast stabilization of vertical size after changes in sync frequency conditions. The free-running frequency f

fr(v)

is determined by the resis-

tor R

VREF connected to pin 23 and the capacitor CVCAP con-

nected to pin 24. 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 reference. Therefore the value of R

VREF must not be

changed. Capacitor C

VCAP should be used to select the free-

running frequency of the vertical oscillator in accordance with the following formula:

The AGC of the vertical oscillator can be disabled by setting control bit AGCDIS via the I²C-bus. Aprecise external current has to be injected into VCAP (pin 24) to obtain the correct vertical size. This special application mode can be used when the vertical sync pulses are serrated (shifted); this condition is found in some display modes, e.g. when using a 100Hz up converter for video signals.

Application hint: VAGC (pin 22) has a high input impedance during scan. Therefore, the pin must not be loaded externally otherwise non-linearities in the vertical output currents may occur due to the changing charge current during scan.

Adjustment of vertical size, VGA overscan and EHT compensation

There are four different ways to adjust the amplitude of the differential output currents at VOUT1 and VOUT2. 1 Register VGIN changes the vertical size without affect-

ing any other output signal of the IC. This adjustment is meant for factory alignments.

2 Register VSIZE changes not only the vertical size, but

also provides the correct tracking of all other related waveforms (see section”Tracking of vertical adjustments”). This register should be used for user adjustments.

3 For the VGA350 mode register VOVSCN can activate a

+17% step in vertical size.

4 VSMOD (pin 21) can be used for a DC controlled EHT

compensation of vertical size by correcting the differential output currents at VOUT1 and VOUT2. The EW waveforms, vertical focus, pin unbalance and parallelogram corrections are not affected by VSMOD.

Adjustment of vertical position, vertical linearity and vertical linearity balance

Register VOFFS provides a DC shift at the sawtooth outputs VOUT1 and VOUT2 (pin 13 and 12) without affecting any other output waveform. This adjustment is meant for factory alignments.

Register VPOS provides a DC shift at the sawtooth output VOUT1 and VOUT2 with correct tracking of all other related waveforms (see Section “Tracking of vertical adjustments”). This register should be used for user adjustments. Due to the tracking the whole picture moves vertically while maintaining the correct geometry.

Register VLIN is used to adjust the amount of the vertical S-correction in the output signal. This function can be switched off by control bit VSC.

Register VLINBAL is used to correct the unbalance of vertical S-correction in the output signal.

Tracking of vertical adjustments

The adjustments via registers VSIZE, VOVSCN and VPOS also affect the waveforms of horizontal pincushion, vertical linearity (S-correction), vertical linearity balance, focus parabola, pin unbalance and parallelogram correction. The result of this interaction is that no readjustment of these parameters is necessary after an user adjustment of vertical picture size and vertical picture position.

Adjustment of vertical moire cancellation

To achieve a cancellation of vertical moire (also known as ‘scan moire’) the vertical picture position can be modulated by half the vertical frequency. The amplitude of the modulation is controlled by register VMOIRE and can be switched off via control bit MOD.

Horizontal pincushion (including horizontal size, corner correction and trapezium correction)

EWDRV (pin 11) provides a complete EW drive waveform. The components horizontal pincushion, horizontal size, corner correction and trapezium correction are controlled by the registers HPIN, HSIZE, HCORT, HCORB and HTRAP.

The corner correction can be adjusted separately for the top (HCORT) and bottom (HCORB) part of the picture.

The pincushion (EW parabola) amplitude, corner and trapezium correction track with the vertical picture size (VSIZE) and also with the adjustment for vertical picture position (VPOS). The corner correction does not track with the horizontal pincushion (HPIN). Further the horizontal pincushion amplitude, corner and trapezium correction track with the horizontal picture size, which is adjusted via register HSIZE and the analog modulation input HSMOD. If the DC component in the EWDRV output signal is increased via HSIZE or Ihsmod, the pincushion, corner and trapezium component of the EWDRV output will be reduced by a factor of

The value 14.4V is a virtual voltage for calculation only. The output pin can not reach this value, but the gain (and DC bias) of the external application should be such that the horizontal deflection is reduced to zero when EWDRV reaches 14.4V. HSMOD (pin 31) can be used for a DC controlled EHT compensation by correcting horizontal size, horizontal pincushion, corner and trapezium. The control range at this pin tracks with the actual value of HSIZE. For an increasing DC component V

The complete waveform is also multiplied internally by a signal proportional to the line frequency [which is detected via the current at HREF (pin 28)]. This mode is to be used for driving EW diode modulator stage which require a voltage proportional to the line frequency.

2. Mode 2

The EW drive waveform does not track with the line frequency. This mode is to be used for driving EW modulators which require a voltage independent of the line frequency.

Output stage for asymmetric correction waveforms [ASCOR (pin 20)]

This output is designed as a voltage output for superimposed waveforms of vertical parabola and sawtooth. The amplitude and polarity of both signals can be change by registers HPARAL and HPINBAL via the I²C-bus.

Application hint: The TDA4856 offers two possibilities to control registers HPINBAL and HPARAL.

1. Control bit ACD = 1

The two registers now control the horizontal phase by means of internal modulation of the PLL2 horizontal phase control. The ASCOR output (pin 20) can be left unused, but it will always provide an output signal because the ASCOR output stage is not influenced by the control bit ACD.

2. Control bit ACD = 0

The internal modulation via PLL2 is disconnected. In order to obtain the required effect on the screen, pin ASCOR must now be fed to the DC amplifier which controls the DC shift of the horizontal deflection. This option is useful for applications which already use a DC shift transformer.

If the tube does not need HPINBAL and HPARAL, then pin ASCOR can be used for other purposes, i.e. for a simple dynamic convergence.

Dynamic focus section [FOCUS (pin 32)]

This section generates a complete drive signal for dynamic focus applications. The amplitude of the horizontal parabola is internally stabilized, thus it is independent of the horizontal frequency. The amplitude can be adjusted via register HFOCUS. Changing horizontal size may require a correction of HFOCUS. To compensate for the delay in external focus amplifiers a ‘pre-correction’ for the phase of the horizontal parabola has been implemented. The amount of this pre-correction can be adjusted via register HFOCAD. The amplitude of the vertical parabola is independent of frequency and tracks with all vertical adjustments. The amplitude can be adjusted via register VFOCUS.

FOCUS (pin 32) is designed as a voltage output for the superimposed vertical and horizontal parabolas.

B+ control function block

The B+ control function block of the TDA4856 consists of an Operational Transconductance Amplifier (OTA), a voltage comparator, a flip-flop and a discharge circuit. This configuration allows easy applications for differnet B+ control concepts. See also Application Note AN96052: “B+ converter Topologies for Horizontal Deflection and EHT with TDA4855/58”.

GENERAL DESCRIPTION

The non-inverting input of the OTA is connected internally to a high precision reference voltage. The inverting input is connected to BIN (pin 5). An internal clamping circuit limits the maximum positive output voltage of OTA. The output itself is connected to BOP (pin 3) and to the inverting input of the voltage comparator. The non-inverting input of the voltage comparator can be accessed via BSENS (pin 4).

B+ drive pulses are generated by an internal flip-flop and fed to BDRV (pin 6) via an open-collector output stage. This flip-flop is set at the rising edge of the signal at HDRV (pin 8). 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 flip-flop and, therefore, the open-collector stage at BDRV is floating again.

I²C-bus autosync deflection controller for PC monitors TDA4857

66

An internal discharge circuit allows a well defined discharge of capacitors at BSENS. BDRV is active at a LOW-level output voltage (see Fig. 22), thus it requires an external inverting driver stage.

The B+ function block can be used for B+ deflection modulators in many different ways. Two popular application combinations are as follows:

• Boost converter in feedback mode (see Fig. 22)

In this application the OTA is used as an error amplifier with a limited output voltage range. The flip-flop is set on 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 no reset is generated within a line period, the rising edge of the next HDRV pulse forces the flip-flop to reset. The flip-flop is set immediately after the voltage at BSENS has dropped below the threshold voltage V

RESTART(BSENS).

• Buck converter in feed forward mode

This application uses an external RC combination at BSENS to provide a pulse width which is independent from the horizontal frequency. The capacitor is charged via an external resistor and discharged by the internal discharge circuit. For normal operation the discharge circuit is activated when the flip-flop is reset by the internal voltage comparator. The capacitor will now 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 flip-flop 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 flip-flop. When the voltage at BSENS reaches the threshold voltage VRESTAR T(BSENS), the discharge circuit will be disabled automatically and the flip-flop 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, references, start-up procedures and protection functions

The TDA4857 provides an internal supply voltage stabilizer for excellent stabilization of all internal references. An internal gap reference, especially designed for low-noise, 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.

If eithr the supply voltage is below 8.3V or no data from the I²C-bus has been received after power-up, the internal soft start and protection functions fo not allow any of those outputs [HDRV, BDRV, VOUT1, VOUT2 and HUNLOCK] to be active.

For supply voltages below 8.3V the internal I²C-bus will not generated an acknowledge and the IC is in standby mode. This is because the internal protection circuit has generated a reset signal for the soft start register SOFTST. Above

8.3V data is accepted and all registers can be loaded. If the register SOFTST has received a set from the I²C-bus, the internal soft start procedure is released, which activates all above mentioned outputs.

If during normal operation the supply voltage has dropped below 8.1 V, the protection mode is activated and HUNLOCK (pin 17) changes to the protection status and is floating. This can be detected by the microcontroller.

This protection mode has been implemented in order to protect the deflection stages and the picture tube during start-up, shut-down and fault conditions. This protection mode can be activated as shown is Table 3.

I²C-bus autosync deflection controller for PC monitors TDA4857

67

When the protection mode is active, several pins of the TDA4857 are forced into a defined state:

HDRV (horizontal driver output) is floating BDRV (B+ control driver output) is floating HUNLOCK (indicates, that the frequency-to-voltage converter is out of lock) is floating (HIGH-level via external pull-up resistor) CLBL provides a continuous blanking signal The capacitor at HPLL2 is discharged.

If the soft start procedure is activated via the I²C-bus, all of these actions will be performed in a well defined sequence.

Power dip recognition

In standby mode the I²C-bus will only answer with an acknowledge, when data is sent to control register with subaddress 1AH. This register contains the standby and soft start control bit.

If the I²C-bus master transmits data to another register, an aknowledge is given after the chip address and the subaddress; an acknowledge is not given after the data. This indicates that only in soft start mode data can be stored into normal registers.

If the supply voltage dips under 8.1 V the TDA4857 leaves normal operation mode and changes into standby mode. The microcontroller can check this state by sending data into a register with the subaddress 0XH. The acknowledge will only be given on the data if the TDA4857 is active.

Due to this behavior the start-up of the TDA4857 is defined as follows. The first data that is transferred to the TDA4857 must be sent to the control register with subaddress 1AH. Any other subaddress will not lead to an acknowledge. This is a limitation in checking the I²C-busses of the monitor during start-up.

BLOCK AND CONNECTION DIAGRAM

Description of the functions

Figure 1 shows the block diagram of LM1281, in conformity with the pin layout of the IC. Every channel accepts both the video signal and the OSD signal at the input anplifier (A1). Also the video/OSD changeover signal passes either the video signal or the OSD signal through LM1281, or is connected with the input amplifier for control purposes. The next contrast adjustment block is a drive adjustment type one. The reference level for the DC return circuit is set by means of the RGB cutoff adjustment pin (PIN 25). Attention must be paid to the fact that the blank clamp gate is active when it is stuck at the LOW state. Under ordinary circumstances, these pins are controlled by means of the standard TTL signal.
