Note :

1. An RC network is connected to this input. Typical value for the resistor is 27k

Ω 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.
