Integrated Circuit

Video IF, Chroma Deflection

Description:

The NTE15035 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.
