Vertical sync separation for 1250i/50
When HV FREQ2 = 01000, the vertical sync separation for the 1250i/50 is accomplished through the use of a special
circuit. The phase of the VD-out (pin 13) depends on the H-SYNC timing shown in the figure below. There is no VD-out
when there is no H-SYNC input.
In the manual sync processing mode (A-SYNC = OFF), use READ BUS functions, V-SYNC-W and H, V FORMAT (or H,
V FREQ DET) to detect the 1250i/50.
Note: The tailing edge of the VD-OUT has a jitter. Use the leading edge only.
HD width
HD-OUT width is selectable by HD WIDTH as below. A setting in which HD WIDTH = 1 (NARROW) is recommended
for the 1125/50p/60p format owing to crosstalk from HD-OUT to video signals causing spike noise on video signals.

HD/VD input amplitude
When a 5.6 k
is added before the input pin like the following figure, 5.0 Vp-p pulse input is allowed. However, the
acceptable minimum amplitude then becomes 2.0 Vp-p.
