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).
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. The limiter consists of AC coupled amplifier stages. The minimum input amplitude for limiting is typical 1mVrms.
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.
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 sandcastle signal and is available starting with the highest level : burstkey, line blanking (=flyback pulse) and vertical blanking.
• 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 I2C bus, SL, and can be used for search tuning and OSD. In automatic mode (FOA/FOB=00) the coincidence detector switches for out of lock condition the PHI-1loop to fast to ansure fast horizontal catching.
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. In this mode the divider is always reset at the standard value even if the vertical sync pulse is missing.
• 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%. The horizontal tracking can be switched off by I2C bus function HCO(Horiz. Compensation). A second function of this pin is for overvoltage protection, XPR(X-ray PRotection). XPR is set to “one” when the voltage on the pin exceeds 3.9 Volts and can be read by I2C bus.
• 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). In Y/C modes the video signal follows a direct path with 160ns delay so as to ensure similarity with chroma path delay.
• 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).
RGB processing and control This paragraph can be divided into : - YUV/RGB processing - RGB-control (1) YUV/RGB processing • The main functions are : - Y-signal processing/black stretcher - (B-Y)/(R-Y) signal processing/matrixing - Dynamic skin tone correction - Second RGB insertion • Y-signal processing/black stretcher Internally the luminance signal is clamped and supplied to the RGB matrix circuit (via black stretcher).
RGB signal selection has three modes to choose from: - RGB (composite) - fast RGB insertion (R1ING1INB1IN) - OSD mode Before the RGB signal selection the RGB signals are clamped to a similar DC level during burstkey period. Selection is controlled by the RGB insertion input switch. Fast insertion on the RGB inputs is made active/inactive via the I2C bus(IE1). With the I2C bit IN1 the status of the insertion switch input is sensed.
For fast insertion on RIN, GIN, BIN 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) • Blue stretcher The Blue stretcher can be divided into two stretch-frunction - the Standard blue stretcher - the Extended blue stretcher The blue stretcher reduces the R- and G- signals by 14% when
• Continuous Cathode Calibration (CCC) The Continuous Cathode Calibration (CCC) loop (or two point stabilisation loop) is an auto-tuning loop which stabilises th black level (offset) as well as the cathode drive level (gain) of each gun of the CRT sequentially and independently on alternating fields. In case of no stabilisation, the transfer characteristic changes as function of temperature and ageing of the tube. The CCC-loop can be divided into two loops : - a black level stabilisation loop.
Power Supply STR-S6708 (1) VIN 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 VIN 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.
(5) Stand-By Mode When going into light load mode such as remote control standby mode, internal impedance at a signal terminal of a microcomputer gets higher. Then the microcomputer have the current, I1, which has been bypassed from C9 through R11 and D10 by the function of a microcomputer, flow into the base of Q4 to turn it on.
(7) OCP (overcurrent protection) function Overcurrent protection is performed pulse by pulse by directly detecting collector current of the power transistor. Configuration of the OCP circuit is shown at the right. Detecting voltage is set to -1V below a reference point of GND(ground). In addition, since the detecting voltage is set by a comparator, very stable characteristics against temperature is achieved and drift of the detecting voltage against temperature change is almost 0V.
