Advanced PAL/NTSC Encoder
The MC13077 is a high quality RGB/YUV to NTSC/PAL encoder with
Composite Video and S–Video outputs. The IC integrates the color
difference and luma matrix circuitry, chroma modulators, subcarrier
oscillator, and logic circuitry to encode component video into a composite
video signal compatible with the NTSC/PAL standards. The IC operates off a
standard + 5.0 V supply and typically requires less than 75 mA, making it
useful in PC environments. The high degree of integration saves board
space and cost, as only passive external components are required for
operation. The IC is manufactured using Motorola’s MOSAIC™ process and
is available in a 20 pin DIP or SOIC package.

B–Y Clamp storage capacitor. A 0.01 µF
capacitor should be connected from this
pin to ground, unless the pin is used as
an input.
R–Y Clamp storage capacitor. A 0.01 µF
capacitor should be connected from this
pin to ground, unless the pin is used as
an input.

0.7 Vpp AC coupled (100% Color Bars).
If not used as an input the pin is clamped
during sync to 2.4 Vdc. Can be used as a
B–Y input (AC coupled, 350 mVpp, 100%
color saturation). Burst Flag, if disabled
at Pin 18, must be inserted here with the
following signal levels; –170 mV (NTSC),
–121 mV (PAL).
If not used as an input the pin is clamped
during sync to 2.4 Vdc. Can be used as a
R–Y input (AC coupled, 490 mVpp, 100%
color saturation). Burst Flag, if disabled
at Pin 18, must be inserted here with the
following signal level; +121 mV for PAL.

If left unconnected, internally generated
color burst will appear at Pins 2 and 4.
Burst Flag will appear at this pin (18). If
grounded, the Burst Flag will be
disabled. If externally driven from
another source of burst flag, the internal
flags will be overriden.
1.8 Vpp burst flag pulses if unconnected.
PAL/NTSC system switch. If grounded,
the MC13077 will encode NTSC, and if
left open, PAL.
In PAL mode, a PAL squarewave
appears at this pin, the phase of which
can be reset by momentarily forcing the
pin to ground during the high state of
the squarewave.
