MC1372
COLOR TV VIDEO MODULATOR
... an mtegrated circuit used to generate an RF TV signal from
baseband color-difference and luminance signals.
The MC1372 contains a chroma subcamer oscillator, a lead and
lag network, a quasi-quadrature suppressed carrier DSB chroma
modulator, an RF oscillator and modulator, and an LSTTL com-
patrble clock driver with adjustable duty cycle.
The MC1372 is a companion part to the MC6847 Video Display
Generator, providmg and accepting the correct de interconnection
levels. This device may also be used as a general-purpose modulator
wtth a variety of vtdeo signal generating devices such as video games,
test equipment, video tape recorders, etc.
• Single 5.0 Vdc Supply Operation for NMOS
and TTL Compatibility
• Minimal External Components
• Compatible with MC6847 Video Display Generator
• Sound Carrier Addition Capability
• Modulates Channel 3 or 4 Carrier with Encoded Vrdeo Signal
• Low Power Dissipation
• Linear Chroma Modulators for High Versatrlity
• Composrte Vrdeo Signal Generation Capability
• Ground-Referenced Video Prevents Overmodulation

Applications with MC6847 Video Display Generator
The MC1372 may be easily interfaced to the MC6847
as shown in Figure 5. The de levels generated and required
by the VDG are compatible with the MC1372, so that
pins 1, 5, 6, 7, and 9 may be directly coupled to the
appropriate MC684 7 pins. Both integrated circuits as
well as any associated NMOS MPU may be driven from
a common 5 Vdc supply.
Recommended Chroma-Luma Signals
A chroma modulatron angle of 100° was chosen to
facrl tate a desirable selection of colors with a minimum
number of input s;gnal levels. The following table demon-
strates applicable signal levels for a variety of colors
