43
32fH VCO
Connect the ceramic
oscillator for horizontal
oscillation.
The oscillator to be used
is CSBLA503KECZF30,
made by Murata
electronics.
44
NC
None connect PIN.
These pins connect to
GND.
45
AFC filter
Connect the filter for
horizontal AFC.
The frequency of the
horizontal output varies
depending on the voltage
at this pin.
DC
46
DEF GND
The GND pin of DEF
block.
47
SYNC.
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.
48
NC
None connect PIN.
These pins connect to
GND.
49
HD output
(1) When BUS HD-OUT
= 0
Output the HD pulse
(pulse duration: 1
s)
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.
