NTE855
Integrated Circuit
Color TV Video Monitor
Description:
The NTE855 is an integrated circuit in a 14鈥揕ead DIP type package used to generate an RF TV signal
from baseband color鈥揹ifference and luminance signals. This device contains a chroma subcarrier
oscillator, a lead and lag network, a quasi鈥搎uadrature suppressed carrier DSB chroma modulator,
an RF oscillator and modulator, and an LSTTL compatible clock driver with adjustable duty cycle. The
NTE855 may be used as a general鈥損urpose modulator with a variety of video signal generating de-
vices such as video games, test equipment, video tape recorders, etc.
