Integrated Circuit Small–Signal Subsystem for Color TV

NTE Electronics 

Note 10. The functions in–sync/out–of–sync and transmitter identification have been combined on this pin. The capaci-

tor is charged during the sync pulse and discharged during the time difference between gating and sync pulse.

Note 11. The vertical scan is synchronized by means of a divider system. Therefore no adjustment is required for the

ramp generator. The divider detects whether the incoming signal has a vertical frequency of 50 or 60HZ and

corrects the vertical amplitude.

Note 12. To avoid screenburn due to a collapse of the vertical deflection, a continuous blanking level is inserted into the

sandcastle pulse when the feedback voltage of the vertical deflection is not within the specified limits.

Note 13. Starting point tuner takeover at 1 = 0.2mA. Takeover to be adjusted with a potentiometer of 47kΩ.
