(note 5) 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 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 fo r charge pump power supply by extracting the sink component of the input video signal (synchronous is olation) and by detecting its fall, the por tion around the v-syncrhonization of this i c output may be reduced when the pseudo v signal without cut-in pul se 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 must be as shortened as possible. (note 3) the wiring from c-out (3pin), c-in(5pin), y-in (7pin) to 75 must be as shortened as possible. v cc mute dc tdk c1608 jb oj 475k tdk c1608 jb 1c 475k tdk c1608 jb 1c 225k tdk c1608 jb 1c 105k tdk c1608 jb 1c 105k tdk c1608 jb 1c 104k tdk c1608 jb 1c 104k h l(open) mute through c(pin3) pin4 active (input signal) signal on no signal off standby off
