DAEWOO MTZ 522 NF DRIVER
Geometry processing With the TDAA is possible to implement automatic geometry alignment, because all parameters are adjusted via the I2C bus. Which standard can be decoded depends on the external Xtals used. Two Xtal pins 34and 36 are Daewoo MTZ 522 NF so normally no external switching is required.

The I. This is important, because the X-tal frequency of the colour decoder is also used to calibrate many internal circuit. The burst phase detector locks the Xtal oscillator with the chroma burst signal. The phase detector operates during the burst key period only, to prevent disturbance of the PLL by the chroma signal. Two gain modes provide: They are implemented as gyrator circuits tuned by tracking to the frequency of the chroma Xtal oscillator. The contrast and brightness control and the peak white limiter operate on both internal and external RGB signals R,G and B each have their own, independent gain control to compensate for the difference in phosphor efficiencies of the picture tube: The nominal amplitude is about 2V black to white, at nominal input signals and control settings.
TDAA has a black current stabilization loop, that automatically adjust the black level to the cut-off voltage of the picture tubes three gun cathodes. Since no current is flowing when the voltage the cathode is equal to the cut-off voltage of the tube, the loop stabilizes at a very small gun current. This "black current" of the three guns is measured internally and compared with a reference current, to adjust the black level of RGBout. The black level loop is active during 4 lines at the end of the vertical blanking. In the first line the leakage current is measured max. In the next three lines the black levels of the three guns are adjusted. At switch-on of the TV receiver the black current stabilization circuit is not yet active and RGBout are blanked. Before the first measurement pulses appear, 0. During the measuring lines RGBout will supply 4V pulses to the video output stages.
Then the black current stabilization circuit is active. After a waiting time of about 1. This value is made higher than the The Cloche filter is a gyrator-capacitor type. Its frequency is calibrated in the vertical retrace period. Pin 7 is a decoupling for the Cloche reference. Pin 8 is the reference capacitor for the PLL The voltage variation during field scan at this Daewoo MTZ 522 NF should be lower than 2 mVresulting in a capacitor of nF.
The sandcastle input pin 1 5 is connected to TDAA pin 41 and is used for generation of the blanking periods and provides clock information for the identification circuit. This is demodulated by a PLL demodulator, that uses the reference frequency at Daewoo MTZ 522 NF I and a bandgap reference to obtain the desired demodulation characteristic.
The ON-time is controlled by changing a current charged by C1, which is as the result of that the detection winding of pin of T, which detects a change of voltage in a secondary side, connected to the sensing terminal Pin 7 has the current in accordance with an Daewoo MTZ 522 NF signal from an output voltage detection circuit an error amplifier built in. As an AC input voltage to the power supply gets the higher and a load current the smaller, the current flowing to the SENS terminal gets the larger, and the ON-time gets the shorter. A threshold voltage of COMP. Daewoo MTZ 522 NF
Quasi-resonant operation By inputting the voltage of winding of pin of T which is synchronized with the energy discharge time of a secondary winding, pin14 or 15 of T, to the INH terminal through D and R, quasi-resonant operation can be achieved. Even after the discharge of energy Daewoo MTZ 522 NF a secondary winding is completed, VINH does not immediately increases.
When it gets lower than VTH1, the transistor turns on. While being in remote control stand-by mode, the output voltage is kept on providing to the secondary side and the power transistor operates at A class mode.
Therefore, it enables to hold an oscillation frequency in light mode below 20KHz typical. Detecting voltage is set to -1V below a reference point of GND ground. As the sustaining current of the latch circuit is A maximum when VIN terminal voltage is 4V, the Daewoo MTZ 522 NF supply circuit sustains the off state as long as current of A minimum flows to VIN terminal from a start-up resistor.
In order to prevent a malfunction to be caused by a noise and so on, delay time is provided by C1 incorporated in the IC and, therefore, the latch circuit operates when the OVP or TSD circuit is in operation, or an external signal input is provided for about 10 sec or longer. In addition, even after the latch circuit start operating, Daewoo MTZ 522 NF constant voltage regulator Reg circuit is in operation and the circuit current is at high level. As a result, VIN terminal voltage rapidly decreases. When the latch circuit is on, VIN terminal voltage increases and decreases within the range from 4.
Cancellation of the latch is done by decreasing VIN terminal voltage below 3. The power supply can be restarted after disconnecting an AC input to the power supply once.
