Note
1
Video signal
input
2.4 V
(sync tip)
500 mVp-p
(80%
modulation)
Sync tip clamp input. It
is used by AC coupling.
Video modulation depth
is set by level of signal
input on this pin.
White clip level for IC is
set internally for DC, but
it will change by the high
frequency-factor.
2
Sound
signal input
0 V
(Normal
Mode)
350 mVp-p
(100% FM
modulation)
Sound modulation depth
is set by level of sound
signal input on this pin.
Sound pre-emphasis is
applied before this pin.
This pin is also used for
switching test mode.
Normally this pin is used
at 0 V DC (used by AC
coupling).

Note 1: Internal Oscillation Mode OFF
Note 2: External Input Mode OFF
As reference signal,
either 4-MHz crystal
resonator can be
connected to this pin for
internal oscillation or
external signal can be
input.
External Input Mode can
be selected using I2C
bus or by pulling up this
pin using external
resistor in Internal
Oscillation Mode.

: external input
3.4 V or lower
: internal oscillation
