Video control combination circuit with automatic cut-off control
GENERAL DESCRIPTION The TDA4580 is a monolithic integrated circuit which performs video control functions in television receivers with a colour difference interface. For example it operates in conjunction the multistandard colour decoder TDA4555. The required input signals are: luminance and negative colour difference -(R-Y) and -(B-Y), and a 3-level sandcastle pulse for control purposes. Analogue RGB signals can be inserted from two sources. One with full performance adjustment possibilities. RGB output signals are available for driving the video output stages. This circuit provides automatic cut-off control of the picture tube. Features Capacitive coupling of the colour difference, luminance and RGB input signals with black level clamping Two sets of analogue RGB inputs via fast switch 1 and fast switch 2 First RGB inputs and fast switch 1 in accordance with peritelevision connector specification Saturation, contrast and brightness control acting on first RGB inputs

2. The value of the colour difference input signals, -(B-Y) and -(R-Y), is given for saturated colour bar with 75% of maximum amplitude. 3. Capacitive coupled to a low ohmic source; recommended value 600 (max.). 4. At pin 19 for V19-24 2,0 V, no further decrease of contrast is possible. 5. The peak drive limiting of output signals is achieved by contrast reduction. The limiting level of the output signals is equal to the voltage V9-24, adjustable in the range 5 to 11 V. After exceeding the adjusted limiting level at peak drive limiter will not be active during the first line. 6. The average beam current limiting acts on contrast and at minimum contrast on brightness (the external contrast voltage at pin 19 is not affected). 7. At nominal brightness the black level at the output is 0,3 V ( -10% of nominal signal amplitude) below the measuring level. 8. The internal control voltage can never be more positive than 0,7 V above the internal contrast voltage. 9. Matrix equation a) V(R-Y),V(B-Y): output of NTSC decoder of PAL type demodulating axis and amplitudes b) V(G-Y) (1), V(R-Y) (note 1), V(B-Y) (note 1): for NTSC modified CD signals; equivalent to demodulation with the following axes and amplification factors:- c) (B-Y) (1) demodulator axis: 0 d) (R-Y) (1) demodulator axis: 115 (PAL 90) e) (R-Y) (1) amplification factor: 1,97 (PAL 1,14) f) (B-Y) (1) amplification factor: 2,03 (PAL 2,03) g) V(G-Y) (1) = -0,27 V(R-Y) (1) - 0,22 V(B-Y) (1). 10. During clamping time, in each channel the black level of the inserted signal is clamped on the black level of the internal signal behind the matrix (dependent on brightness control). 11. During warm-up time of the picture tube, the RGB outputs (pins 1, 3 and 5) are blanked to minimum output voltage. An inserted white pulse during the vertical flyback is used for beam current detection. If the beam current exceeds the threshold of the warm-up detector at pin 26, the cut-off current control starts operating, but the video signal is still blanked. After run-in of the cut-off current loop, the video signal will be released. The first measuring pulse occurs in the first complete line after the end of the vertical part of the sandcastle pulse. The absolute minimum vertical part must contain 9 line-pulses. The cycle time of the counter is 63 lines. When the vertical pulse is longer than 61 lines, the IC is reset to the switch-on condition. In this event the video signal is blanked and the RGB-outputs are blanked to minimum output voltage as during warm-up time. During leakage current measurement, all three channels are blanked to ultra-black level 1. With the measuring level only in the controlled channel, the other two channels are blanked to ultra-black level 1. The brightness control shifts both the signal black level and the ultra-black level 2. The brightness control is disabled from line 4 to the end of the last measuring line (see Fig.4). With the most adverse conditions (maximum brightness and minimum black level 2) the blanking level is located 30% of nominal signal amplitude below the cut-off measuring level.

12. The given blanking times are valid for the vertical part of the sandcastle pulse of 9 to 15 lines. If the vertical part is longer and the cut-off lines are outside the vertical blanking period of 18, 22 or 25 lines respectively, the blanking of the signal ends with the end of last of the three cut-off measuring pulses as shown in Fig.7. 13. The sandcastle pulse is compared with three internal thresholds (proportional to VP) to separate the various pulses. The internal pulses are generated when the input pulse at pin 10 exceeds the thresholds. The thresholds are for: a) Horizontal and vertical blanking b) Horizontal pulse c) Clamping pulse V10-24 = 1,5 V V10-24 = 3,5 V V10-24 = 7,0 V

14. The outputs at pins 1, 3 and 5 are emitter followers with current sources and emitter protection resistors. 15. The value of the cut-off control range for the positive RGB output signals is given for a nominal output signal. If the signal amplitude is reduced, the cut-off range can be increased. 16. The gain data is given for a nominal setting of the contrast and saturation controls, measured without load at the RGB outputs (pins 1, 3 and 5).

SOLDERING Introduction

TDA4580

There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
