Description
Inputs sync on video (sync at negative
polarity). Connects in series a 1 µF
capacitor and a 270 Ω resistance to
input signals.
Selects output processing of HD
(H. Drive Pulse) at a VD interval.
Input at TTL level.
When Low level is selected, HD is not
output at a VD interval.
When High level is selected, HD is
output at the VD interval.
Resistance connecting pin for
reference current source of clamp
pulse output circuit, and connects 12
kΩ resistance to GND. When a 12 kΩ
resistance is connected, a 100 µA
current flows through this pin (pulse
width is approximately 300 ns).
Clamp pulse output pulse width is
varied by changing the value of the
resistance.
∗Use a metal film resistor with an
accuracy of ±1 %
