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