For the selected pin, keyed clamp
is applied to the input so that the
clamp voltage of the output signal
becomes constant when the
signal is provided. Diode clamp is
applied to the input when there is
no signal. When no pin is
selected and at CS-REC, diode
clamp is applied to the input
regardless of whether or not the
signal is provided.

Diode clamp is applied to the input
when there is no signal at pin 1 or
when the pin is not selected. For
RGB through, feedback clamp is
applied from the output to the
input.

The signal that has been selected
and keyed clamped (excluding
chroma) is amplified and output
from the emitter follower.
The constant current of emitter
follower is 2.5mA when the built-in
LPF is selected and 7.5mA when
it is not selected.
