NJM1372A
TV VIDEO MODULATOR
■ GENERAL DESCRIPTION
The NJM1372A is an integrated circuit to be used to generate an RF TV signal from
baseband color-difference and luminance signals.
The NJM1372A contains a chroma subcarrier oscillator, lead and lag network, a
quasi-quadrature suppressed carrier DSB chroma modulator, an RF oscillator and
modulator, and a TTL compaible clock driver with adjustable duty cycle.
This device may also be used as a general-purpose modulator with a variety of video
signal generating devices such as video games, test equipment, video type recorders, etc.
