(7) Driving of input pins

Drive pins 9 , 16 , 17 and 18 at low impedance because they

are clamped by IC input.

(8) I/O relation between sync signal and burst signal

during the period V

I/O relation between sync signal and burst signal

(9) Setting of V DL and Ys DL in superimpose mode

1) V DL is used to adjust the timing of RGB encode signal and

VIDEO IN signal.

2) Ys DL is used to adjust the timing of RGB encode signal and Ys

IN signal.

3) In case that signals are input to C.SYNC IN, RGB IN, VIDEO IN

or Ys IN at the same timing, set V DL and Ys DL based on the

delay volume as below.

V DL = Y DL (Refer to (4)) + 10 (nsec)

Ys DL = Y DL - 10 (nsec)
