(Note 2)
Position the decoupling
capacitor of VCC-GND
as near as possible to
this IC.
(Note 5)
Use the input capacity value within a range of
0.1
μF to 1μF while checking the sag
condition of the output waveform.
(Note 4)
For these two capacities;
Temperature
characteristic B rank
(±10%)
Electrostatic tolerance
K rank(±10%)
and Withstand voltage
of 6.3V or more are
recommended.
(Note 6)
As the minus power supply in this IC generates the clock for charge pump power supply by extracting the sink component
of the input video signal (synchronous isolation) and by detecting its fall, the portion around the V-syncrhonization of this IC
output may be reduced when the pseudo V signal without cut-in pulse is inserted as in the case of certain analog VCR
special play (search). On the contrary, there is no problem when the pseudo V signal has the cut-in pulse. Pay due attention
on this fact during use.
(Note 1)
The wiring from MIX-OUT(13Pin),
Y_OUT(Pin15) to 75
Ω must be as
shortened as possible.
(Note 3)
The wiring from C-OUT
(3Pin), C-IN(5Pin), Y-IN
(7Pin) to 75
Ω must be as
shortened as possible.
