29 CXA1870s description of operation 1. synchronizing and picture distortion correction systems the video signals (2 vp-p standard) input to pins 40 and 41 are led to the horizontal and vertical sync separation circuits for sync separation. the horizontal sync signal is output from pin 39 with positive polarity. this horizontal sync signal is compared with the signal obtained by 1/32 frequency dividing the 32 fh vco output using the ceramic oscillator (frequency: 503.5 khz) to detect a phase difference. the error voltage resulting from the phase difference is applied to the h oscillator after attenuating the medium and high frequency components by a lag-lead filter. the phase of the h oscillator output is compared and shifted to match the phase of the h deflection pulse (flyback pulse) input from pin 31, and then output from pin 29. after the vertical sync signal is synchronized to the input signal by the v countdown system, a sawtooth wave is generated by charging and discharging the capacitor attached externally to pin 26. agc is performed to ensure that the amplitude of the sawtooth wave is maintained constant regardless of the vertical frequency of the input, after which the sawtooth wave passes through the picture distortion correction circuit and is output from pin 24. note that there is no need to adjust the free running frequency for either the h or v oscillator. when voltage of 3 v or more is applied to pin 30, the h drive output is held at low level. a time constant circuit is included to protect against overvoltages, and h drive is output normally when high voltage input continues for less than 7 v cycles. to release holddown, the ic must be turned off and then started up again. note) when the external capacitance at pin 27 is used with 0.1 f below of recommended value, vd output at pin 24 may be unstable. when changing capacitance value, use it more than 0.047 f. 2. y/c system the y/c system has the following three input systems. composite video input (1 vp-p/2 vp-p) 2 systems (the gain can be switched between 0 and 6 db for both systems.) y/c separation input (2 vp-p) 1 system the y signal (specified input level 2 vp-p) input to pin 7 is passed through the sub-contrast control, chroma trap (or delay line), delay line, sharpness control, noise reduction, clamp and auto pedestal circuits. the signal is then mixed with the color difference signal, passed through the clamp and y/c mix circuits again, and input to the rgb interface system block. since a built-in chroma trap is provided, the video signal can be directly input. trap frequency adjustment is not necessary as a dummy filter is provided inside the ic and feedback is applied using the 3.58 mhz signal generated by a crystal oscillator for reference. when the chroma trap is off, the y system frequency response is approximately 8 mhz, ? db for r, g and b outputs. sharpness control is delay line type with a variable pre/over ratio. dynamic picture control consists of pulling in the signal below 40 ire to the black side so that the signal black peak held by pin 8 becomes the pedestal level. the chroma signal (specified input level, burst 570 mvp-p, or video signal 2 vp-p) input to pin 9 is passed through the acc, tot, color control (saturation control) and killer detection circuits, after which the burst locked vco oscillation output is detected as the carrier. (the detective output lpf is a quadruple.)
30 CXA1870s the signal is then separated into color difference signals r-y, b-y and g-y by the matrix circuit, passed through the y/c mix circuit, and input together with the y signal to the rgb interface system block. the detective axis (japan/us) can be switched by the i 2 c bus register. 3. rgb interface system ys/ym switching is performed according to the amplitude of the osd rgb input blanking signal input from pin 11. 0 to 1.5 v tv (y/c input) 1.5 to 3.5 v tv ? db 3.5 to 5.5 v black the r, g and b signals of the y/c system pass through the rgb switch (blue and black on/off) and receive picture control. these signals are mixed with the digital r, g and b signals (specified input level 0 to 5 v dc) input from pins 12, 13 and 14, passed through the dynamic color, gamma correction, bright control, drive adjustment (r channel is fixed, g and b channels are variable.), cut-off adjustment (r channel is fixed, g and b channels are variable.) and auto cut-off dc level shift circuits, and then output from pins 16, 18 and 20 as the r, g and b signals. the rgb output amplitude has a limit voltage whose setting value can be controlled with the i 2 c bus register. the digital r, g and b signals are mainly used for on screen display of channels, etc. and the display level can be set with the i 2 c bus register. the signal input to pin 23 (abl in) is compared with the internal reference voltage and is then integrated by the capacitor connected to pin 25 (abl lpf) for picture and brightness control. picture abl mode and combined picture abl and brightness abl mode can be switched with the i 2 c bus register. note) when the digital r, g and b signals and osdblk signal are not used, connect pins 11, 12, 13 and 14 to gnd. auto cut-off for white balance, drive control (gain control between r, g and b outputs) and cut-off control (black side dc level control) are involved. this ic uses the i 2 c bus register for drive control. for cut-off control, a loop is formed between the ic and crt to achieve auto cut-off control. this auto cut-off arrangement makes it possible to compensate for crt changes with time. to absorb the crt variance, the cut-off voltages of the g and b outputs are adjusted by the i 2 c bus register. the auto cut-off loop is configured as described below. (1) r, g and b reference pulses for auto cut-off, shifted 1h each in the order mentioned, are added to the top of the picture. (2) the ik of each of the r, g and b outputs is converted to a voltage and input to pin 21. (3) the voltage input to pin 21 is compared with the reference voltage in the ic to change the dc level of the reference pulses. the loop mentioned above determines the shift level of the r, g and b outputs and lets the capacitances connected to pins 15, 17 and 19 hold the dc shift level during the 1 v period. if the voltage at any one of pins 15, 17 or 19 is less than 4.2 v, the status register ik (bit 6) becomes ?? use this information to blank the r, g and b outputs with the i 2 c bus register. the positions of the reference pulses can be changed by the i 2 c bus register.
