(Note 2)
Use the input capacity value within a range of 0.1
F
to 1
F while checking the sag condition of the output
waveform.
(Note 1)
Position the decoupling
capacitor of VCC-GND as
near as possible to this IC.

(Note 3) 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 4) Wiring from V OUT (pin 9) to 75 must be as short as possible.
(Note 5)
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 duri ng use.
