PIN NAME
16 VCC
FUNCTION
VCC pin.
Connect 12V (typical).
17 Y output
Output pin for luminance signal on which Y
is processed.
Max. output current value : 2mA (min. drive
resistance value : 3.8k)
INTERFACE
18
Black area
hold
Used to connect filter which detects black
area of input luminance signal.
Voltage changes depending on black area
of input signal pin.
Black area detection of bus control can
vary threshold of black area detect.
19
Y output for
VM
Y output pin for VM (Velocity Modulation).
Maximum output current value : 2mA
(minimum drive resistance : 2.4k).
20
Black area
output
Output pin for black area detected by black
area hold circuit. Outputs DC current
depending on input black area. Larger
black area, higher pin voltage. Control is
possible using output of this pin, depending
on input signal black area.
