    Circuit Description Vision IF amplifier, AFC, video demodulator The IF signal from the tuner is fed through a SAW filter to the differential IF input (pin 48 and 49). The first IF stage consists of 3 AC-coupled amplifiers with a total gain control range of over 66 dB. The reference carrier for the video demodulator is obtained by a PLL carrier regenerator (eliminating notch filter compromises, as in reference tuned circuits for passive carrier regeneration).
  • Page 35 Circuit Description Sound The main functions are : - Limiter - PLL-Demodulator - Pre-amplifier and mute - Audio switch - Volume controlled amplifier • Limiter The sound carrier signal is supplied to this limiter input via an external bandpass filter. This external bandpass filter is used for selectivity, the internal filter at the pin is used for noise reduction.
  • Page 36 The charge (or attack) current is 1mA, the discharge (or decay) current is 200nA. This equals a current ratio of 5000. The time constant is defined by the AVL capacitor. The DC voltage (1-5V) across the AVL capacitor controls a gain stage that stabilizes the audio output level. Horizontal and vertical synchronization The main functions are : - Horizontal sync separator...
  • Page 37 The PHI-2 circuit shifts the horizontal drive, pin 40, such that the picture position on screen is constant. The flyback input pin 41 is combined with the sandcastle output. This combined function provides a three level sand- castle signal and is available starting with the highest level : burstkey, line blanking (=flyback pulse) and vertical blank- ing.
  • Page 38 • Coincidence detector (Synchronization Lock SL) The coincidence detector detects whether the incoming CVBS signal is synchronized with the horizontal oscillator, thus whether the PHI-1 loop is in-lock. The output is available by I C bus, SL, and can be used for search tuning and OSD.
  • Page 39 3. Standard TV-norm : divider ratio 525(60Hz) or 625(50Hz) When the system is switched to the narrow window (standard mode) it is checked whether the incoming vertical sync pulses are according to the TV norm, if so IVW=1, When 15 standard TV-norms are counted the divider system is switched to the standard divider ratio mode.
  • Page 40 • EHT tracking + overvoltage protection Both the vertical and the E-W drive can be modulated for EHT compensation. This tracking makes the picture size independent of EHT variations due to the beam current. The compensation range is -5 to +5%.

    • Luminance signal processing For luminance processing, the selected video signal is supplied to the H/V sync circuits for sync processing and also to an adjustable delay line (Ons - 320ns, minimum step is 40ns, controlled via bus bits YD0-YD3). The chroma trap is bypassed for no burst transmissions when in own intelligence mode (automode).
  • Page 42 • PAL/NTSC demodulation The 0˚ and 90˚ reference signals from the VCXO are supplied to the HUE phase rotator; it’s outputs (H0, H90) are supplied to the (B-Y) and (R-Y) burst demodulators respectively. The demodulated burst from the (B-Y) demodulator supplies NTSC ident information to the ASM(IDN signal). The demodulated burst from (R-Y) demodulator supplies PAL ident information to the ASM(IDP signal).

Selection is controlled by the RGB insertion input switch. Fast insertion on the RGB inputs is made active/inactive via the I C bus(IE1).
  • Page 45 For fast insertion on R inputs then brightness, contrast and white point RGB is possible RGB output illustration during OSD mode During OSD, the DC level on RGB outputs is 200mV less then DC level on RGB outputs during black current measurement (contrast, brightness and white point RGB are inactive) •...

  • Page 47 Power Supply STR-S6708 (1) V terminal, start-up circuit Astart-up circuit is to start and stop a operation of a control IC by detectiong a voltage appearing at a V terminal (pin-9). At start up of a power supply, when a voltage at the Vin terminal reaches to 8V (typical) by charging up C6 by the function of a start-up resistor, Rs, a control circuit starts operating by the function of the start-up circuit.
