TDA9105 OPERATING DESCRIPTION
GENERAL CONSIDERATIONS Power Supply The typical value of the power supply voltage VCC is 12V. Perfect operation is obtained if VCC is maintained in the limits : 10.8V 13.2V. In order to avoid erratic operation of the circuit during the transient phase of VCC switching on, or switching off, the value of VCC is monitored and the outputs of the circuit are inhibited if VCC < 7.6 typically. In order to have a very good powersupplyrejection, the circuit is internally powered by several internal voltage references (The unique typical value of which is 8V). Two of these voltage references are externally accessible, one for the vertical part and one for the horizontal part. These voltage references can be used for the DC control voltages applied on the concerned pins by the way of potentiometers or digital to analog converters (DAC's). Furthermore it is necessary to filter the a.m. voltage references by the use of external capacitor connected to ground, in order to minimize the noise and consequently the "jitter" on vertical and horizontal output signals. DC Control Adjustments The circuit has 10 adjustment capabilities : 2 for the horizontal part, 2 for the E/W correction, 4 for the vertical part, 2 for the Dynamic Horizontal phase control. The corresponding inputs of the circuit has to be driven with a DC voltage typically comprised between 2 and 6V for a value of the internal voltage reference of 8V. Figure 5 : Example of Practical DC Control Voltage Generation
VREF
In order to have a good tracking with the voltage reference value, it's better to maintain the control voltages between VREF /4 and 3/4 VREF. The input current of the DC control inputs is typically very low (about a few A). Depending on the internal structure of the inputs, it can be positive or negative (sink or source). HORIZONTAL PART Input section The horizontal input is designed to be sensitive to TTL signals typically comprised between 0 and 5V. The typical threshold of this input is 1.6V. This input stage uses an NPN differential stage and the input current is very low. Figure 6 : Input Structure
H-SYNC
1.6V
Concerning the duty cycle of the input signal, the following signals may be applied to the circuit. Using internal integration, both signals are recognized on condition that Z/T 25%. Synchronisation occurs on the leading edge of the internal sync signal. The minimum value of Z is 0.7s. Figure 7

PLL1 The PLL1 is composed of a phase comparator, an external filter and a Voltage Controlled Oscillator (VCO). The phase comparator is a "phase frequency" type, designed in CMOS technology. This kind of phase detector avoids locking on false frequencies. It is followed by a "charge pump", composed of 2 current sources sink and source (I = 1mA typ.)

The dynamic behaviour of the PLL is fixed by an external filter which integrates the current of the charge pump. A "CRC" filter is generally used (see Figure 9). PLL1 is inhibited by applying a high level on Pin 14 (PLLinhib) which is a TTL compatible input. The inhibition results from the opening of a switch located between the charge pump and the filter (see Figure 8). The VCO uses an external RC network. It delivers a linear sawtooth obtained by charge and discharge of the capacitor, by a current proportionnal to the current in the resistor. typical thresholds of sawtooth are 1.6V and 6.4V (see Figure 10). The control voltage of the VCO is typically comprised between 1.6V and 6V (see Figure 10). The theoreticalfrequencyrange of this VCO is in the ratio 1 3.75, but due to spread and thermal drift of external components and the circuit itself, the effec-
tive frequency range has to be smaller (e.g. 30kHz 85kHz). In the absence of synchronisation signal the control voltage is equal to 1.6V typ. and the VCO oscillates on its lowest frequency (free frequency). The synchro frequencyhas to be always higher than the free frequency and a margin has to be taken. As an example for a synchro range from 30kHz to 85kHz, the suggested free frequency is 27kHz.

TDA9105 OPERATING DESCRIPTION (continued)
The PLL1 ensures the coincidence between the leading edge of the synchro signal and a phase reference obtained by comparison between the sawtooth of the VCO and an internal DC voltage adjustable between 2.4V and 4V (by Pin 15). So a 45phase adjustment is possible (see Figure 11). Figure 11 : PLL1 Timing Diagram

Phase REF1 is obtained by comparison between the sawtooth and a DC voltage adjustable between 2.4V and 4V. The PLL1 ensures the exact coincidence between the signals phase REF and HSYNS . A T/8 phase adjustment is possible.
The two VCO threshold can be filtered by connecting capacitor on Pins 8-9. The TDA9103 also includes a LOCK/UNLOCK identification block which senses in real-time Figure 12 : LOCK/UNLOCK Block Diagram
whether the PLL is locked on the incoming horizontal sync signal or not. The resulting information is available on HLOCKOUT output (Pin 2). The block diagram of the LOCK/UNLOCK function is described in Figure 12. The NOR1 gate is receiving the phase comparator output pulses (which also drive the charge pump). When the PLL is locked, on point A there is a very small negative pulse (100ns) at each horizontal cycle, so after R-C filter, there is a high level on Pin 13 which force HLOCKOUT to high level (provided that HLOCKOUT is pulled up to VCC). When the PLL is unlocked, the 100ns negative pulse on A becomes much larger and consequently the average level on Pin 13 will decrease. When it reaches 6.5V, point B goes to low level forcing HLOCKOUT output to "0". The status of Pin 13 is approximately the following : - Near 0V when there is no H-SYNC, - Between 0 and 4V with H-SYNC frequency different from VCO, - Between 4 and 8V when H-SYNC frequency = VCO frequency but not in phase, - Near to 8V when PLL is locked. It is important to notice that Pin 13 is not an output pin and must only be used for filtering purpose (see Figure 12).

Output Section The H-drive signal is transmitted to the output through a shaping block ensuring a duty cycle adjustable from 30% to 50%. In order to ensure a reliable operation of the scanning power part, the output is inhibited in the following circumstances : - VCC too low, - Xray protection activated, - During the horizontal flyback, - Output voluntarily inhibited through Pin 4. The output stage is composed of a Darlington NPN bipolar transistor. Both the collector and the emitter are accessible (see Figure 16). The output Darlington is in off-state when the power scanning transistor is also in off-state. The maximum output current is 20mA, and the correspondingvoltage drop of the output darlington is 1.1V typically. It is evident that the power scanning transistor cannot be directly driven by the integrated circuit. An interface has to be designed between the circuit and the power transistor which can be of bipolar or MOS type. Outputs inhibition The application of a voltage lower than 1V (typ.) on Pin 4 (duty cycle adjust) inhibits the horizontal and vertical outputs. This is not memorised.

X-RAY PROTECTION : the activation of the X-ray protection is obtained by application of a high level on the X-ray input (>8V). Consequences of X-ray protection are : - Inhibition of H drive output, - Activation of composite blanking output. The reset of this protection is obtained by VCC switch off (see Figure 17).

Geometric Corrections The principle is represented in Figure 20. Starting from the vertical ramp, a parabola shaped is generatedfor E/Wcorrection, dynamic horizontal phase control correction, and vertical dynamic Focus correction. The core of the parabola generator is an analog multiplier. The output current of which is equal to : I = k (VRAMP - VDCIN)2. Where VRAMP is the vertical ramp, typically comprised between 2 and 5V, VDCIN is a vertical DC input adjustable in the range 3.2V 3.8V in order to generate a dissymmetric parabola if required (keystone adjustment). In order to keep good screen geometry for any end user preferences adjustment we implemented the possibility to have "geometry tracking". To enable the "tracking" function, the VDCOUT must be connected to VDCIN. It is possible to inhibit VPOS tracking by applying a fixed DC voltage on the VDCIN Pin. This DC voltage in that case must be taken from the vertical reference and adjusted to 3.5V with an external bridge resistor. Due to large output stages voltage range (E/W, BALANCE, FOCUS), the combination of tracking function with maximum vertical amplitude max. or min. vertical position and maximum gain on the DC control inputs may leads to the output stages saturation. This must be avoided by limiting the output voltage by apropriate DC control voltages.

For E/Wpart and Dynamic Horizontal phase control part, a sawtooth shaped differential current in the following form is generated: I' = k' (VRAMP -VDCIN). Then I and I' are added together and converted into voltage. These two parabola are respectively available on Pin 37 and Pin 40 by the way of an emitter follower which has to be biased by an external resistor (10k). They can be DC coupled with external circuitry. EW VOUT = 2.5V + K1' (VRAMP - VDCIN) + K1 (VRAMP - VDCIN)2 K1 is adjustable by EW amp control (Pin 39) K1' is adjustable by KEYST control (Pin 38)

The output connection is the same as the two other corrections (Pins 37-40). It is important to note that the parasitic parabola during the discharge of the vertical oscillator capacitor is suppressed.

The vertical part generates a fixed amplitude ramp which can be affected by a S and C correction shape. Then, the amplitude of this ramp is adjusted to drive an external power stage. The internal reference voltage used for the vertical part is available between Pin 26 and Pin 24. It can be usedas voltage reference for any DC adjusment
to keep a high accuracy to each adjustment. Its typical value is :
V26 = VREF = 8V.
The charge of the external capacitor on Pin 27 (VCAP) generates a fixed amplitude ramp between the internal voltages, VL (VL = VREF/4) and VH (VH = 5/8 VREF).
21/32
TDA9105 OPERATING DESCRIPTION (continued)
VERTICAL PART (continued) Function When the synchronisation pulse is not present, an internal current source sets the free running frequency. For an external capacitor, COSC = 150nF, the typical free running frequency is 100Hz. Typical free running frequency can be calculated by :
f0 (Hz) = 1.5 10
-5
1 COSC (nF)
A negative or positive TTL level pulse applied on Pin 34 (VSYNC) can synchronise the ramp in the frequency range [fmin, fmax]. This frequency range depends on the external capacitor connected on Pin 27. A capacitor in the range [150nF, 220nF] is recommanded for application in the following range : 50Hz to 120Hz. Typical maximum and minimum frequency, at 25C and without any correction (S correction or C correction), can be calculated by : fmax = 2.5 f0 and fmin = 0.33 f0 If S or C corrections are applied, these values are slighty affected. If an external synchronisation pulse is applied, the internal oscillator is automaticaly caught but the amplitude is no more constant. An internal correction is activated to adjust it in less than half a second: the highest voltage of the ramp on Pin 27 is sampled on the sampling capacitor connected on Pin 25 (VAGCCAP) at each clock pulse and a transconductance amplifier generates the charge current of the capacitor. The ramp amplitude becomes again constant. It is recommanded to use a AGC capacitor with low leakage current. A value lower than 100nA is mandatory. Pin 36, Vfly is the vertical flyback input used to generate the composite blanking signal. If Vfly is not used, (VREF - 0.5), at minimum, must be connected to this input. DC Control Adjustments Then, S and C correction shapes can be added to this ramp. This frequency independent S and C corrections are generated internally; their ampli-
tude are DC adjustable on Pin 28 (VSAMP) and Pin 29 (COR-C). S correction is non effective for VSAMP lower than VREF/4 and maximum for VSAMP = 3/4 VREF. C correction is non effective for COR-C grounded and maximum for : COR-C = VREF/4 or COR-C = 3/4 VREF. Endly, the amplitude of this S and C corrected ramp can be adjusted by the voltage applied on Pin 31 (VAMP). The adjusted ramp is available on Pin 30 (VOUT) to drive an external power stage. The gain of this stage is typically 30% when voltage applied on Pin 31 is in the range VREF/4 to 3/4 VREF. The DC value of this ramp is kept constant in the frequency range , for any correction applied on it. Its typical value is : VDCOUT = VMID = 7/16 VREF . A DC voltage is available on Pin 32 (VDCOUT). It is driven by the voltage applied on Pin 33 (VPOS) For a voltage control range between VREF/4 and 3/4 VREF, the voltage available on Pin 32 is : VDCOUT = 7/16 VREF 300mV. So, the VDCOUT voltage is correlated with DC value of VOUT. It increases the accuracy when temperature varies. Basic Equations In first approximation, the amplitude of the ramp on Pin 30 (VOUT) is :
VOUT - VMID = (VCAP - VMID) [1 + 0.16 (VAMP - VREF/2)]
with VMID = 7/16 VREF ; typically 3.5V VMID is the middle value of the ramp on Pin 27 VCAP = V27 , ramp with fixed amplitude. On Pin 32 (VDCOUT), the voltage (in volts) is calculated by : VDCOUT =VMID + 0.16 (VPOS - VREF/2). VPOS is the voltage applied on Pin 33. The current available on Pin 27 (when VSAMP = VREF /4) is : IOSC = 3/8 VREF COSC f COSC : capacitor connected on Pin 27 f synchronisation frequency The recommanded capacitor value on Pin 25 (VAGC) is 470nF. Its ensures a good stability of the internal closed loop.
