3-5 Synchronization system
1) Synchronization stability
Operation is stable with the input signal in
the following range.
· Internal synchronization
-6dB is kept at sync component of
video input as rated value, and video
input
change
when
the
video
component is suddenly varied over 0
to 0.85Vp-p range.
±6dB (at rated value)
· External synchronization
Negative voltage applied to external
sync input tenninal
I to 8Vp-p
2) 'Vertical synchronization
(!)Free run frequency of oscillator
Variable over a 45Hz to 65Hz range
by V.HOLD.
@Free running frequency stability
Within ±2Hz in the above condition
@Interlace ratio
