... Note: 1. Width of vertical blanking pulse on SSC output is proportional to the frame flyback time, the switching level is V other input of the comparator is tied to the frame amplifier output. Application circuit uses the frame flyback generator. Parameter Parameter = 30V, V4/3 with CC2 = 30V, V3/4 with CC2 = 30V CC2 Parameter TDA8215B Min. Typ. Max. Unit 0.06 0 ...

Line Flyback Input (Pin 18) Symbol Switching level Maximum input current at V Limiting voltage at maximum current τ RC network time constant (Note 1) Note network is connected to this input. Typical value for the resistor is 27kΩ and 220pF for the capacitor. A different time constant for RC changes the delay between the middle of the line synchro pulse and the leading edge of the burst key pulse but also the duration of the burst key pulse ...

... TDA8215B Figure 6. Line Oscillator R5 Phase comparator output The oscillator thresholds are internally fixed by re- sistors. The discharge of the capacitor depends on the internal resistor R4. The control voltage is ap- plied on resistor R5. The sync-pulse drives the current in the comparator. The line flyback inte- grated by the external net work gives on pin 13 a saw tooth, the DC offset of this saw tooth is fixed by VC ...
