2) Comp Sync/H sync, V sync input

Connect the composite sync input to pin [6]. For the separate sync input, connect H and V to pins[6] and [8]

respectively. The bias and impedance at pins [6] and [8] are 6 V and 10 k

Ω, respectively.

Waveform shaping and polarity detection are performed by a double threshold converter installed inside.

The internal circuit is as shown in Fig.B. The average DC voltage is set to approximately 0.7 V higher and lower

Thus, as shown in Fig. A, this processor is energized by an input signal 0.7 Vp-p or over when the duty ratio is

small. On the other hand, approximately 1.4 Vp-p is suitable when the duty ratio is large. Fig. C indicates an

allowable standard value for the input duty.
