Video signal input. Performs
diode clamping, with the
clamp capacitance externally
connected. If the mode MUTE
is set High, the charge of the
clamp capacitance is
discharged.
Level adjustment during
recording. The adjustment
range is 1.3V to 2.6V. During
playback, serves as input for
JOG (variable speed
playback) VD pulse and HD
pulse.
V
(Refer to item 3 on Description
of Operation.)
Video signal input for video

clamping, with the clamp
capacitance externally
connected.
Time constant for feedback
clamp circuit in I/O block.
