NTE1790
Integrated Circuit
Video IF, Chroma Deflection
Description:
The NTE1790 combines all the functions required for an NTSC color TV system on a 64–Lead DIP
shrink type plastic package. This device is designed to have wide application capability, from a funda-
mental CTV application to a high–end MPX CTV with quasi–parallel SIF system, with minimal external
parts and adjustments. A quasi–parallel SIF system assures buzz free sound reproduction.
