In that case, the following symptoms will appear. - The control signal appears on the screen. - Loss of synchronization of the video signal Shows the proposed measures on the next page. A case of multiple coaxial transmission: UTC(Up The Coaxial) This is one of a case at the multiplex coaxial transmission used in CCTV. It is a system that control signals of camera multiplexing to the coaxial cable. This system is superimposed on the control signal pulse in the vertical blanking period as shown in Figure. This is because do not affect the video signal.

10 Proposed measures is shift the output DC signal by using the V- terminal (pin 7) of NJU7. The steps are as follows:. A resistor: Rss add between the Ro (7Ω) and V- terminal (7pin).. Reduce Ro (7Ω). By adding a Rss, level of the video signal is attenuated. Example: Level of the video signal will be reduced % at connected Rss = 7Ω and Ro = 7Ω. Therefore, increase % of video output level by changed to Ω the Ro. *Table shows an external resistor value and the swing of video output signal at (pin) =.V, V.. Please evaluation of S/N. It is because the noise of the charge pump may change. Value (typ.) UNIT (pin).
