Description

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.

VTH = 2.7V

(Refer to item 3 on Description

of Operation.)
