NTE NTE7008

NTE7008
Integrated Circuit
Color TV/Video, Chroma, Deflection Circuit
Description:
The NTE7008 is a small–sized multifunctional IC in a 30–Lead DIP type package containing the “video,
chroma, deflection” circuit of a NTSC color TV. Besides being small–sized, this device requires fewer
adjustments and a reduced number of external components. The NTE7008 can be used in conjunction
with the NTE1728 for “VIF–SIF” use or the NTE1773, NTE1797, NTE1855, NTE7085 for “vertical output”
use to perform all color TV signal processing functions.
The polarity of the quadratic differentiation circuit input of the NTE7008 is inverted to facilitate easy
connection of a Tr, L, C, R–used circuit for higher picture quality to the quadratic differentiation circuit
input of the video circuit. The NTE7008 contains a wide–band video circuit (10MHz) and is suited for
use in AV or large–sized sets.
