(3) power supply noise when power supply noise is generated, the internal oscillator cir- cuit does not stabilize, whereby causing horizontal jitters across the picture display. therefore, connect a bypass capacitor be- tween the power supply and gnd. (4) synchronous correction action when switching channel or in the special playback mode (quick playback, rewinding, and so on) of vtr, effect of synchronous correction becomes strong, and distortion of a character is apt to occur because the continuity of video signal is suddenly switched. when the continuity of video signal is out of order, erasure of displayed characters is recommended in a extreme short time to raise the quality of displayed characters. (5) notes on f sc signal input this ic amplifies the subcarrier frequency (f sc ) signal (ntsc, m- pal system: 3.58mhz, pal system: 4.43mhz) input to the oscin pin (17-pin) and generates the composite video signal internally. the amplified f sc signal can be destabilized in the following cases. a) when the f sc signal is outside of recommended operating con- ditions. b) when the waveform of the f sc signal is distorted. c) when dc level in the f sc waveform fluctuates. when the amplified signal is unstable, the composite video signal generated inside the ic is also unstable in terms of syn- chronization with the subcarrier and phase. consequently, this results in color flicker and lost synchroniza- tion when the composite video signal is generated. make note of the fact that this may prevent a stable blue background from being formed. (6) forbidding to stop entering the f sc signal this ic doesnt properly work if the f sc signal is not entered into the oscin pin (pin 17), so dont stop the f sc signal so as to work the ic. to stop the ic, turn the display off (set 0 in the register dspon (address f8 16 ).) (7) forbidding to set data during the period in which the internal oscillation circuit stabilizes a) to start entering the f sc signal when its input is stopped. b) to start oscillating the oscillation circuit for display when its oscillation is stopped. (to assign 1 to the register stop1 (ad- dress f8 16 ) when it is assigned 0, or the like.) c) to turn on the internal bias when it is turned off. (to assign 1 to the register level1 (address f8 16 ) when it is assigned 0.) there can be instances in which data are not properly set in the registers until the internal oscillation circuit stabilizes, so follow the steps in sequence as given below. 1) set 0 in the register dspon (address f8 16 ). (the display is turned off) 2) effect the settings a), b), and c) given above. 3) wait 20 ms (the period necessary for the internal oscillation cir- cuit to stabilize) before entering data. 4) set necessary data in other registers, and make the display ram ready.
