NTE7019
Integrated Circuit
Digital Tuning System Interface for TV Systems
Description:
The NTE7019 is an integrated circuit in a 16Lead DIP type package developed to facilitate the Phase
Lock Loop (PLL) digital tuning system interface for TV systems. Since all the peripheral blocks are
incorporated into this device, the number of peripheral parts can be greatly reduced.
