2. An RC network is connected to this input. Typical value for the resistor is 27k and 220pF for the capacitor. A different time
the other input of the comparator is tied to the frame amplifier output. Application circuit uses the frame flyback generator.
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.
