output
Output the synchronizing
signal that was separated
in the synchronous
separation circuit.
This pin is of the open
collector system. Connect
the pull-up resistor.

49 HD output
(1) When BUS HD-OUT
=0
Output the HD pulse
(pulse duration: 1 µs)
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.
