16 V-Sep.
Connect the filter separating the
vertical synchronization.
17 HD output
(1) When BUS HD-OUT = 0
Output the HD pulse (pulse
duration : 1µs) together with
AFC. This pin also serves as the
external input pin that accepts
BPP (black peak detection
stopping pulse) signal.
(2) When BUS HD-OUT = 1
When AKB mode is ON, the
pulse which covers AKB
reference period is output.
