Supply Voltage
Composite Video output. The external
75 Ω series resistor determines the
impedance of the output. The output will
drive a 75 Ω load through a 75 Ω coax.
Luminance S–Video output. The external
75 Ω series resistor determines the
impedance of the output. The output will
drive a 75 Ω load through a 75 Ω coax.
Chrominance S–Video output. The
external 75 Ω series resistor determines
the impedance of the output. The output
will drive a 75 Ω load through a 75 Ω
coax.
Luminance Output Clamp storage
capacitor. A 0.01 µF capacitor should be
connected from this pin to ground.
Luminance input from the delay line. The
delayed Luma from Pin 10 is applied at
this pin.
Composite Sync input. Negative going
sync should be applied at this pin. The
input has a threshold of 1.4 V.
Four times Subcarrier Frequency Crystal
Oscillator pin. This pin provides for the
connection of the oscillator resonant
element. Pin may also be driven directly
with a 4x subcarrier signal.
External Subcarrier Input. This pin
provides an input to a Phase Detector and
PLL and allows phase–lock of the 4x
oscillator to an external subcarrier
reference. To disable the PLL, this pin
should be grounded. 400 Hz of pull–in and
lock–in range is possible with a crystal.

+ 5.0 Vdc 10%
1.0 Vpp (75% Color Saturation),
1.23 Vpp (100% Color Saturation) at
the 75 Ω load.
1.0 Vpp with sync (100% output) at the
75 Ω load.
885 mVpp (100% output) when at the
75 Ω load.
3.4 Vdc.
500 mVpp of Composite Luma when
100% saturated RGB inputs are applied.
The peak voltage may not exceed V CC .
Minimum voltage should not be less than
0 V. See Figure 2 for input requirements.
300 to 600 mVpp 4x subcarrier input if
the pin is being externally driven.
Approximately 40 mVpp, if a crystal is
being used.
0.10 to 3.0 Vpp (AC coupled) of
subcarrier to phase–lock 4x oscillator or
grounded to disable the PLL.
