The I2C bus is for defining and controlling the signals. the signal is fed for demodulation to either the UOC (for mono FM radio) or by the Micronas MSP34X5 (for stereo FM radio). • RGB amplifier The processing circuits listed above are all integrated in the UOC TV processor. Also some picture improvement features are implemented in this part: • Black stretch This function corrects the black level of incoming signals. which have a difference between the black level and the blanking level.

The surrounding components are for the adaptation of the selected application.9 MHz IF signal is developed and amplified.7 MHz concept. The amount of extension depends upon the difference between actual black level and the darkest part of the incoming video signal level.3 Video Source Selection The Composite Video Blanking Signal (CVBS) from buffer 7201 goes to the audio carrier trap filters (1200 and 1201) to remove the audio signal. The result is made known to the auto system manager. • Video source selection. The PAL/NTSC decoder has an internal clock generator.

Tuner AGC (Automatic Gain Control) will reduce the tuner gain and thus the tuner output voltage when receiving strong RF signals.eps 120401 Figure 9-5 Once the signal source is selected. Adjust the AGC take-over point via the Service Alignment Mode (SAM).2E Circuit Description FM radio (if present) 7200 The FM radio uses the 10. 9. The IC also generates an Automatic Frequency Control (AFC) signal that goes to the tuning system via the I2C bus. The shaped signal is then applied to the IF processor part of the UOC (pos. The tuner AGC starts working when the video-IF input reaches a certain input level and will adjust this level via the I2C bus. 9. This SIF frequency is available at pin 10 of the tuner. The internal input switch selects the following input signals: • Pin 40: terrestrial CVBS input • Pin 42: external AV1 CVBS input • Pin 44: external Side I/O CVBS or AV2 Luminance (Y) input • Pin 45: external AV2 Chrominance (C) input . The received colour burst sub-carrier frequency is used for this.

This trap is switched 'on' or 'off'. the RGB signals at pins 51. This has the advantage that in multi-standard receivers no compromise has to be made for the choice of the SAW filter. L01. 9. The demodulated composite video signal is available at pin 38 and then buffered by transistor 7201. Pin 50 is the input for the insertion control signal called ‘FBL-1’. The tuner AGC signal goes to the tuner (pin 1) via the open collector output (pin 22) of the UOC. 13 41. Correspondingly. where the 38. The signal then goes to pin 40 of IC7200.3. the luminance signal goes to the chroma trap filter. The IF signals then exits the tuner from pin 11 to pass through the SAW filter (position 1002 in case of QSS demodulation and 1003 in case of Intercarrier demodulation). three pulses with a current of 8 mA are generated to adjust the cut off voltage. Brightness reduction starts when the voltage on pin 54 is less than 1. The following additional controls are used: • Black current calibration loop Because of the 2-point black current stabilisation circuit. The horizontal drive starts up in a soft start mode. Contrast and brightness reduction of the RGB output signals is therefore proportional to the voltage present on this pin. before being output to the CRT board (pins 56.2E 9. which is running at twice the line frequency. 7312 and 7313. which exceed this 80% level. both the black level and the amplitude of the RGB output signals depend on the drive characteristics of the picture tube. During set switch ‘off’.7 RGB Amplifier From outputs 56. the RGB signals are applied to the analogue output amplifiers on the CRT panel. This has as a consequence. The starting frequency during switch on is therefore about 2 times higher than the normal value. making the ‘EHT0’ line ‘high’. the PLL is closed in such a way that only very small phase corrections are necessary. It starts with a very short TON time of the horizontal output transistor. The ‘EHTinformation’ line on pin 11 is intended to be used as a ‘X-ray’ protection.3 V (limiter not active). The OSD/TXT signal from the microprocessor is mixed with the main signal at this point. This voltage is rectified by diode 6413 and fed to the emitter of transistor 7405. the horizontal drive (pin 30) is switched 'off' immediately.1 Deflection Horizontal Drive The horizontal drive signal is obtained from an internal VCO. This frequency is divided by two. which converts it to R. This prevents the CRT from being overdriven. The filament voltage is monitored for ‘no’ or ‘excessive’ voltage. to adjust the picture level in order to compensate for changes in the beam current.4 Synchronisation Inside IC7200 (part D). so that the discharge is not visible on the screen. During the first frame.7 V. The ‘EHTinformation’ line (Aquadag) is also fed back to the UOC IC7200 pin 54. Therefor this block inserts the cut-off point measuring pulses into the RGB signals during the vertical retrace period. which could otherwise cause serious damage in the line output stage. 57 and 58 of IC7200. The horizontal drive signal exits IC7200 at pin 30 and goes to 7401. The signal is amplified and coupled to the base circuit of 7402.3.

When the nominal value is reached. If the ‘H-drive’ is stopped. During the switch-off period.8 V. When the IC is switched ‘on’. The correction is dependent on the luminance. and adapt the output level and gain of the circuit when necessary. This current ensures that the picture tube capacitance is discharged. The LOT provides the extra high voltage (EHT). Dynamic skin tone correction This circuit corrects (instantaneously and locally) the hue of those colours which are located in the area in the UV plane that matches the skin tone. The voltage on pin 54 is normally 3. They are then fed to the H. 9. The ‘Hflybk’ signal is fed to pin 31 to phase lock the horizontal oscillator.and V-drive circuits and to the OSD/TXT circuit for synchronisation of the On Screen Display and Teletext (or Closed Caption) information. The TOFF of the transistor is identical to the time in normal operation. to lock the first control loop to the incoming signal. This is done with the measurement pulses during the frame flyback.8 V. The R-signal is amplified by a circuit built around transistors TS7311. the ‘+8V’ voltage goes to pin 9 of IC7200. the RGB drive signals are switched on. During the second frame. that a change in the gain of the output stage will be compensated by a gain change of the RGB control circuit. saturation and distance to the preferred axis. • The YUV signal is then fed to the colour matrix circuit. pin 11 will become low again. The 2-point black level system adapts the drive voltage for each cathode in such a way that the two measuring currents have the right value. which drives the picture tube cathodes. the horizontal driver transistor. The reference used for this purpose is the DC voltage on pin 54 (BLCIN) of the TV processor. • Blue stretch This function increases the colour temperature of the bright scenes (amplitudes which exceed a value of 80% of the nominal amplitude). Contrast reduction starts when the voltage on pin 54 is lower than 2. brightness and saturation to be adjusted.6 RGB Control The RGB control circuit enables the picture parameters contrast. If this voltage goes above 6.Circuit Description • White stretch This function adapts the transfer characteristic of the luminance amplifier in a non-linear way depending on the average picture content of the luminance signal. The ‘Hdrive’ signal is available at pin 30. so that TS7401 cannot switch ‘on’ during the flyback time. The ‘EWdrive’ signal for the E/W circuit (if present) is available on pin 15. 9. the vertical and horizontal syncpulses are separated. These ‘H’ and ‘V’ signals are synchronised with the incoming CVBS signal. For bright pictures.3. This will drive the line output transformer (LOT) and associated circuit.5 9. Now the horizontal drive is again switched on via the slow start procedure. When the set is switched on. L01.5. the ‘Hdrive’ signal is suppressed until the frequency is correct. 57 and 58). Pin 55 (BLKIN) of the UOC is used as the feedback input from the CRT base panel. 9. transistor 7405 will conduct. where it drives transistor 7400 to make linearity corrections in the horizontal drive. This effect is obtained by decreasing the small signal gain of the red and green channel signals. the horizontal output transistor. 9. The ‘on’ time is slowly increased to the nominal value in 1175 ms. three pulses with a current of 20 mA are generated to adjust the ‘white drive’. • Beam current limiting A beam current limiting circuit inside the UOC handles the contrast and brightness control for the RGB signals. It operates in such a way that maximum stretching is obtained when signals with a low video level are received. the black current control circuit generates a fixed beam current of 1 mA. When this protection is activated (when the voltage exceeds 6 V). Additionally automatic gain control for the RGB signals via cut-off stabilisation is achieved in this functional block to obtain an accurate biasing of the picture tube. The system checks whether the returning measuring currents meet the requirements. The supply voltage for the amplifier is +160 V and is derived from the line output stage. by using a combination of the user menus and the remote control. This will immediately switch off the horizontal drive (pin 30) via the slow stop procedure. 5.
