NTE15042
Integrated Circuit
Digital Tuning System Interface for TV Systems
Description:
The NTE15042 is an integrated circuit in a 16鈥揕ead 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.
