Integrated Circuit
Single Chip TV NTSC System
Description:
The NTE7058 combines all the functions required for an NTSC color TV system in a 64–Lead DIP
type plastic package. This device is designed to offer a wide capability of applications from fundamen-
tal CTV to high–end MPX CTV with a quasi–parallel SIF system, requiring minimal external parts and
adjustments. A quasi–parallel SIF system assures buzz–free sound reproduction.
